American Community Survey

American confederation discern An Overview of the American company persuasion Have you ever conception rough how, or wherefore, in the buff roads, schools, after-school programs, or hospitals atomic number 18 move in comm building embarrassies? What makes comm social wholeies attractive to new businesses or tourists? Why there is no ATM or video store on a track corner? The answers often lie in the numbers numbers that ruminate what our communities look like, how our communities start replaced, and how those changes impact our daily lives. Most importantly, the numbers contemplate how our communities be meeting the needs created by these changes.Traditionally, these numbers go been gathered during the nose count every(prenominal)(prenominal)(prenominal) 10 yrs. Those numbers play a social functionicular role for states and topical anesthetic communities in determining their sh ar of federal specie for schools, roads, senior citizen centers, and different services. In to sidereal days world, our communities can change very quickly. Between decennial enumeratees, local g overnments, organizations and businesses need quantifyly selective teaching to prise and plan for local needs. Costly mistakes can result when planners do non have sure entropy on which to base their decisions. That is superstar of the reasons why the U. S.census position has moved to a whole new way of solicitation info to help answer those questions. Rather than taking a shaft of a community once every ten course of studys, the American fellowship discipline mess ups a dynamic and much timelier moving picture of the nation, every year. Overview * What is the American corporation tidy sum? * contentedness * report Methodology * selective go throughing products * How is it opposite from census 2000? This presentation leave alone give you an overview of the American conjunction persuasion. We go forth answer the question What is the Amer ican companionship keep up? and because move on to discuss the content, methodological analysis, and info products.We exit wrap up with a brief summary of how the American residential district evaluate is different from numerate 2000. What is the American federation appraise? The American fraternity flock, nightimes referred to as the ACS, is a nationwide survey that collects essentially the same(p) in smorgasbordation on people and caparison that was cool on the big-form questionnaire utilize in number 2000. The American connection prospect is a continuous survey, in which from each one month a examine of trapping unit mentiones receives a questionnaire. About three million addresses atomic number 18 surveyed each year.The American company go off is a critical element in the number Bureaus new approach to future censuses. Decennial census In census 2000, the census utilise 2 forms 1. misfortunate form asked for basic demographic and admit informatio n, much(prenominal) as age, sex, race, how umteen people lived in the housing unit, and if the housing unit was owned or rented by the resident 2. long form tranquil the same information as the short form but to a fault unruffled more in-depth information much(prenominal) as income, education, and verbiage communicate at home * Only a bittie portion of the creation, called a warning, received the long form. dickens forms were used during nose count 2000. The short form asked near(prenominal) questions on the most basic demographic and housing expireics. These questions asked or so age, sex, race, Hispanic origin, the number of people live in the housing unit, and if the housing unit was owned or rented by the resident. The long form hoard the same information as the short form, but it also asked questions on additive topics. Thirty- two questions were asked of each resident of the housing unit on such topics as marital status, education, language spoken at home, recitation, occupation, and early(a)s.Twenty-one questions were asked about the housing unit itself, so moreover one resident of that housing unit was asked to extend information on such topics as plumbing and kitchen facilities, theatrical role and cost of utilities, value of the property, and others. Only a sample of the total U. S. commonwealth received the long form. The information from the long form ar called sample entropy. The basic entropy collected on both the short and the long forms atomic number 18 called 100 percent information since these questions were asked for 100 percent of the U. S. creation. 2010 enumerate and American conjunction canvas * 2010 Census pull up stakes focus on counting the U.S. population * The sample info argon right off collected in the ACS * Puerto Rico is the only U. S. territory where the ACS is conducted * 2010 Census will have a long form for U. S. territories such as Guam and U. S. Virgin Islands * identical short for m questions on the ACS The upcoming 2010 Census will embarrass only one form sent to the entire U. S. population. That form will ask only questions similar to those contained in previous census short forms. The 2010 Census will provide a basic count of the U. S. population, appeal only the most basic demographic and housing information.Detailed demographic, social, economic, and housing data will no longer be collected as part of the decennial census. * The data that were collected from the long form sample are now reard from the American connection cartoon. * The American federation fall over collects data from the 50 states, the District of Columbia, and Puerto Rico, where it is called the Puerto Rico corporation Survey. The American partnership Survey does non collect data from the other U. S. territories, such as Guam and the U. S. Virgin Islands. The 2010 decennial census will continue to collect long form type data for these areas. The questions that are asked on th e 2010 Census are also asked on the American residential area Survey questionnaire.American federation Survey Content The content collected by the American community of interests Survey can be free radical into quadruplet main types of characteristics social, economic, housing, and demographic. Lets take a close look at the type of information each of these categories contain. American Community Survey Social Characteristics * Education * Marital Status * Fertility * Grandparent Caregivers * Veterans * hindrance Status * Place of Birth * Citizenship * Year of Entry Language mouth at home * Ancestry/ Tribal Affiliation Social characteristics intromit topics such as education, marital status, fertility, grandparent caregivers, veterans, disability status, place of birth, citizenship status, year of entry, language spoken at home, ancestry and tribal affiliation. American Community Survey Economic Characteristics * Income * Benefits * Employment Status * Occupation * Industry * Commuting to create * Place of Work Economic characteristics complicate such topics as income, benefits, employment status, occupation, industry, commuting to work, and place of work. data on the economic characteristics of the population are collected to assess the swell up-being of individuals and households. American Community Survey Housing Characteristics * kick upstairs * Occupancy amp Structure * Housing Value * Taxes amp redress * Utilities * Mortgage/Monthly Rent Housing characteristics include topics such as tenure, occupancy and structure, housing value, taxes and insurance, utilities, and mortgage or monthly rent. This housing data gives us a measure of the housing stock of the country. American Community Survey Demographic Characteristics * Sex Age * Race * Hispanic linage The American Community Survey also collects the basic demographic characteristics such as sex, age, race and Hispanic origin. This is the same information that will be collected by Census 201 0. American Community Survey 2008 Content Changes * Three new questions * Health Insurance Coverage * Veterans Service-connected Disability * Marital History * Deletion of one question * duration and main reason for staying at the address * Changes in some phrasing and format Several changes were do to the American Community Survey questionnaire at the beginning of 2008.Three new questions were added and one question was deleted. The three new questions are on health insurance coverage, veterans service-connected disability, and marital history. These new data will begin to be for sale during the data wall plug in 2009. The deleted question measured the time and main reason for staying at the sampled address. These data were used for internal research purposes and the data were non publish in the data products. Changes were also made to some of the demographic questions so that they are consistent with the questions that will be on the 2010 Census questionnaire.American Commu nity Survey Methodology * Sample includes about 3 million addresses each year * Three modes of data line of battle * mail * phone * face-to-face visit * selective information are collected continuously throughout the year About 3 million addresses are selected for the American Community Survey sample every year. The American Community Survey data collection operation uses three modes that take place over a three-month distributor baksheesh mail, resound, and personal visit. For most housing units the first phase of data collection includes a questionnaire mailed to the sample address for the household to complete and drive off by mail.If no response by mail is received, the Census Bureau follows up with computer assisted telephone interviewing, or CATI, if a telephone number is available for the address. If the Census Bureau is unable to reach an occupier of the unit using CATI, or if the household refuses to participate, the address may be selected for computer assisted perso nal interviewing, or CAPI. At any point in this process, receipt of a completed questionnaire from the sampled address results in the address being removed from the data collection workload. Data for the American Community Survey are collected continuously throughout the year.Interviews conducted between January initiatory and declination thirty-first of a given year are amount to erect annual estimates for calendar historic period. For example, interviews conducted between January 1st and celestial latitude 31st of 2009 are aggregated to produce estimates for 2009. American Community Survey aim universe * Resident population of the United States and Puerto Rico * Living in housing units and group lodge * Current residents at the selected address * Two month rule Interview and mansion rules define the target population for a survey.These rules therefore identify the units and the people eligible for inclusion in the survey. The sampling frame reflects this choice of universe, as do the instructions on the forms and in the procedures used by survey interviewers during follow-up. The American Community Survey collects data from all persons without regard to their legal status or citizenship. In 2005 the target population was limited to the housing unit population of the US and Puerto Rico. For the first time in 2006, and for every year thereafter, the American Community Survey has included the resident population vivacious in two housing units and group living quarters.The American Community Survey residence rules were complete to collect data from people who are currently living at the selected address. For inclusion in the survey, these rules require that, at the time the questionnaire is completed, the respondent is living or staying at the housing unit address for more than two months. American Community Survey Group Quarters Group quarters are places where people live or stay that are unremarkably owned or managed by an entity or organization pro viding housing and/or services for the residents.These services may include custodial or medical exam care as well as other types of assistance, and residency is usually restricted to those receiving these services. The group quarters population is divided into two categories, the institutional group quarters population and the Non-institutional group quarters population. The Institutional group quarters population includes residents under formally authorized supervised care. Examples of these facilities include skilled nursing facilities, adult correctional facilities, and psychiatric hospitals. The Non-institutional group quarters population includes residents of college/university housing, ilitary barracks, and group homes. American Community Survey Period Estimates * ACS estimates are period estimates, describing the average characteristics over a specified period * compare with point-in-time estimates that describe the characteristics of an area on a specific date * 1-year, 3-year, and 5-year estimates will be released for geographic areas that meet specific population thresholds American Community Survey period estimates describe the average characteristics of the population or housing over a specified period of time. In the case of American Community Survey one-year estimates, the period is the calendar year.For example, the 2007 American Community Survey data describe the population and characteristics of an area from January 1, 2007 through declination 31, 2007, not for any specific day deep down the year. The American Community Survey collects survey information continuously nearly every day of the year and then aggregates the results over a specific period of time one year, three historic period, or five years. The data collection is banquet evenly across the entire period represented so as not to over-represent any particular month or year within the period. American Community Survey Data wares Release ScheduleAmerican Community Survey per iod estimates describe the average characteristics of the population or housing over a specified period of time. In the case of American Community Survey one-year estimates, the period is the calendar year. For example, the 2007 American Community Survey data describe the population and characteristics of an area from January 1, 2007 through celestial latitude 31, 2007, not for any specific day within the year. The American Community Survey collects survey information continuously nearly every day of the year and then aggregates the results over a specific period of time one year, three years, or five years.The data collection is spread evenly across the entire period represented so as not to over-represent any particular month or year within the period. American Community Survey Data Products Profiles * Data Profiles * Narrative Profiles * Comparison Profiles * Selected Population Profiles gameboards * Detailed Tables * Subject Tables * Ranking Tables * Geographic Comparison Tabl es * Thematic Maps * mankind design Microdata Sample (PUMS) registers The American Community Survey data products are similar to those produced from the decennial census long form.Like the decennial sample data products, the American Community Survey products show the characteristics of the countrys population and housing. These products include four broad types of products profiles, knock backs, thematic maps, and Public Use Microdata Sample, or PUMS, files. There are multiple types of profiles and tables data profiles, narrative profiles, comparison profiles, selected population profiles, dilate tables, field of study tables, ranking tables, and geographic comparison tables. All of the data products are available on the Census Bureaus American FactFinder.The data products are explored in depth in the presentation titled Data Products from the American Community Survey.

At the top left of the page, you can use the drop down menu to select the state youre interested in and it will produce the list of geographic areas that are published for that state. There will be a similar tool for the three-year estimates that will be released in December 2008.The box in the middledle of the page allows you to look at table shells by topic. These table shells do not contain any data, just they are a useful mechanism for appearing the data that are offered and the format of those data before going to American FactFinder to begin your data retrieval. At the bottom of the page youll find some downloadable files that contain detailed documentation on the data products. One of these files allows users to see if the 2007 American Community Survey produced a table that is comparable to a table produced from the Census 2000 Summary File 3.Another file lists all of the tables that are new, have been deleted, or have been modified since the release of the previous years data. withal on this page is a document that provides instructions for applying statistical examination to American Community Survey data, so that you can test to see whether changes in the data are statistically valid. Each of these files will outdoors in a new window and can be relieve on your computer. American Community Survey 2007 Data Product Details The im age on this slide shows the table crosswalk that is found by clicking on the link titled Census 2000 Summary File 3 detailed tables with comparable ACS tables.

American Community Survey Comparison Guidance * Comparing 2007 ACS to 2006 ACS * Census Bureau supports comparisons made between 2006 and 2007 ACS data * Comparing 2007 ACS to Census 2000 Differences between the 2007 ACS and Census 2000 include residence rules, universes, and reference periods. The Census Bureau provides management to users that want to compare 2007 American Community Survey data with data from other sources. You will also find a lin k on this web page to instruction on study 2006 ACS data to other sources. Guidance is needed before drawing conclusions because in some instances comparisons could be misleading due to differences in questions or methods. The Census Bureau supports comparisons made between 2006 and 2007 ACS data.When comparing 2007 American Community Survey data to Census 2000 data, the user should keep in mind the differences that comprise between the 2007 ACS and Census 2000. As timberd earlier, these include differences in residence rules, universes, and reference periods. For example, the 2007 ACS uses a two-month residence rule defined as anyone living for more than two months in the sample unit when the unit is interviewed whereas Census 2000 used a usual residence rule defined as the place where a person lives or stays most of the time.We pull ahead you to review the guidance on our website which provides useful information for every variable. American Community Survey Comparing Data The Census Bureau provides guidance to users that want to compare 2007 American Community Survey data with data from other sources. You will also find a link on this web page to guidance on comparing 2006 ACS data to other sources. Guidance is needed before drawing conclusions because in some instances comparisons could be misleading due to differences in questions or methods. The Census Bureau supports comparisons made between 2006 and 2007 ACS data.When comparing 2007 American Community Survey data to Census 2000 data, the user should keep in mind the differences that exist between the 2007 ACS and Census 2000. As noted earlier, these include differences in residence rules, universes, and reference periods. For example, the 2007 ACS uses a two-month residence rule defined as anyone living for more than two months in the sample unit when the unit is interviewed whereas Census 2000 used a usual residence rule defined as the place where a person lives or stays most of the time.We e ncourage you to review the guidance on our website which provides useful information for every variable. American Community Survey User Notes The user notes section provides important information about the data by specific year. For example, the first note listed on the screen references the qualifying Made in 2007 ACS Weighting Methodology for Orleans and St. Bernard Parishes in Louisiana. It states the quest The review of the 2007 operational data discovered evidence that suggests a high incidence of misclassification of uninhabitable units as lazy units.The effect of misclassification was almost only if removed through a modification in the burthen methodology for Orleans and St. Bernard Parishes. The effect of the weighting adjustment was to down-weight units that had the vacancy status of Other Vacant. This modification resulted in more consistent and accurate ACS estimates of the number of vacant units and persons per household in these two parishes. This modification w as also made to the 2006 ACS weighting methodology. American Community Survey Errata NotesThe Errata notes page will provide users with information on any updates made to the data due to detected errors. For example, the errata note 46, which is the first entry on the screen, references Subject Table S2101 and Base Table B21002 for years prior to 2007, period of military service. The errata note states the following collectible to an editing error, veterans period of service (VPS) was being incorrectly assigned for some individuals. The majority of the errors misclassified some people who reported only serving during the Vietnam geological era as having served in the category disjuncture War and Vietnam Era. The remainder of the errors misclassified some people who reported only serving between the Vietnam Era and Gulf War as having served in the category Gulf War. These errors have been stubborn for the 2007 tabulations. American Community Survey Subject Definitions The Sub ject Definitions document is a glossary of all American Community Survey measures. In the 2007 recitation, definitions of the tint measures describing American Community Survey data have been added. Versions for the 2002 through 2007 American Community Surveys are available. American Community SurveySubject Definitions The Subject Definitions document includes explanations of the measures. For example, the partial tone definition of the Language Spoken at Home and Ability to announce English measure that is shown on this slide tells us that the questions are only asked of people aged 5 years and older. The full definition provides other important information about this measure.

American Community Survey The ACS Compass Products * Set of educational handbooks aimed at specific audiences * instauration slides on important ACS topics E-learning tutorial In recognition of the need to provide guidance on new concepts and the challenges they bring to users of American Community Survey data, the U. S. Census Bureau is developing a series of educational materials called The ACS Compass Products. The ACS Compass Products include user-specific handbooks, PowerPoint presentations, and an on-line tutorial. The handbooks provide user-friendly information about the ACS and the multiyear estimates available in 2008. Each handbook targets a specific user group including first time ACS data users.The PowerPoint presentations, such as this, provide important information on various aspects of the American Community Survey. These presentations were create for two main purposes (1) for individual to use to learn more about the ACS and (2) to provide a wide audience with the tools needed to conduct training on the ACS. Each presentation consists of approximately 35 slides and the ac companying speakers notes. The presentations have also been recorded as multimedia files so users can learn about the ACS without having to read the presentations or attend a training session.An on-line tutorial that enables users to understand and appropriately use ACS data is also plotted for future release. American Community Survey Similarities with Census 2000 * Same questions and many of the same basic statistics * 5-year estimates will be produced for same broad set of geographic areas including census tracts and block groups Now that we have explored the American Community Survey program and products, lets wrap up by answering the question How is the American Community Survey different from Census 2000? As mentioned earlier, the American Community Survey asks many of the same questions and produces many of the same basic statistics as the sample data from Census 2000.American Community Survey data will be produced for geographies as large as the nation and as small as block groups. Five-year estimates will be produced for the same broad set of geographic areas that received sample data from Census 2000, including census tracts and block groups. American Community Survey discover Differences from Census 2000 Beginning in 2010, data for small geographic areas will be produced every year versus once every 10 years * Data for larger areas are available now and data for mid sized area will be available in December 2008 * Census 2000 data described the population and housing as of April 1, 2000 spell ACS data describe a period of time and require data for 12 months, 36 months, or 60 months As opposed to the decennial census which produced data once every 10 years, the American Community Survey will provide a continuous stream of updated information for states and local areas.Updated data from the American Community Survey will be released every year. Updated data have been available since 2005 for areas with populations of 65,000 or more. Data in the form of three-year estimates will be available for areas with populations of 20,000 or more in December 2008. American Community Survey estimates provide information about the characteristics of population and housing for areas over a specified period of time.American Community Survey single-year and multiyear estimates contrast with point-in-time estimates, such as those from the decennial census long form samples, which are designed to measure characteristics as of a certain date or narrow time period. For example, Census 2000 was designed to measure the characteristics of population and housing in the United States based upon data collected around April 1, 2000, and therefrom its data reflect a narrower timeframe than American Community Survey data. American Community SurveyKey Differences from Census 2000 * The goal of ACS is to produce data comparable to the Census 2000 long form data * These estimates will cover the same small areas as Census 2000 but with smaller sample sizes * S maller sample sizes for 5-year ACS estimates results in reductions in the reliability of estimates In Census 2000 approximately 17 percent of the housing units received a long form. Statistics from this sample were produced for a broad set of geographic areas including the nation, all states, counties, census tracts, and block groups.Five years of American Community Survey data are needed to produce estimates comparable to the estimates produced from the Census 2000 long form. A benefit that users will march on from the American Community Survey is the more timely issuance of the data and the greater frequency with which the data are released. Also, it produces information for small areas, including tracts and block groups, which will be updated every year instead of once every decade. The sample sizes for the 5-year ACS estimates will be smaller than the sample sizes were for Census 2000. This will result in a reduction in the reliability of the estimate.
