4 Today s Presentation Goals and Outline Goals 1. To provide some suggestions on some data types and data sources that might be of use to those who work with or on behalf of young children in Illinois; 2. To briefly show how IECAM uses Census data to present its demographic and risk factors data. Outline 1. Overview: What is Census Bureau? What does it do? 2. Quick and easy information 3. Population Estimates Program 4. American Community Survey 5. American FactFinder 6. IPUMS-USA 7. IECAM Experience: How does IECAM get the data for updating demographic and some risk factors data? 4

5 1. Overview What is the Census Bureau? What does it do? Census Bureau is a federal bureau that collects data on demographic, economic, and housing characteristics of the U.S. population. Data are primarily collected through decennial census, as well as a survey instrument called long form, then replaced by a continuous survey called the American Community Survey (ACS), and other programs, such as Population Estimates Program. Census web sites (main site: provide an amazing wealth of data. Census data are useful to distribute federal and state funds and to help governments of all levels, local planners and communities, and private sectors to make informed decisions. People visiting the Census web sites have various purposes: o o o o Getting a quick overview of data for their area Finding data from a particular census program or survey (such as PEP or ACS) Finding data on a particular topic, such as poverty Finding data to create estimates for specific needs (such as what IECAM does!) 5

30 4. American Community Survey (ACS) Overview Continuous nationwide survey (not a feature of the Census Web site) Replaced the former long form of the decennial census 3 million addresses surveyed annually 1-, 3-, and 5-year estimates are released annually Period rather than point-in-time estimates 30

31 4. American Community Survey (ACS) Period estimates 1-year estimates: more timely but only areas with population of 65,000 or more 3-year estimates: areas with population of 20,000 or more 5-year estimates: greater statistical reliability, all areas IECAM uses 5-year estimates (e.g., recently uploaded: 2013 ACS 5-year estimates) 31

32 4. (ACS) More information from the Census Bureau ACS Main page 32

33 4. American Community Survey (ACS) More information from the Census Bureau What Is the ACS? ACS Guidance for Data Users 33

34 5. American FactFinder Via Then: 1. Click Data tab 2. Click Data Tools & Apps tab 3. Click American FactFinder Either way, we will arrive at FactFinder Main. By default: Community Facts Other mode of search: e.g. Advanced Search Alternatively, access FactFinder directly through this link: 34

35 5. American FactFinder Four modes of data search: 1. Community Facts 2. Guided Search 3. Advanced Search 4. Download Center 35

36 5. American FactFinder Search mode: Community Facts Data query box Final table 36

37 5. American FactFinder Search mode: Guided Search Data query steps Final table 37

42 6. PUMS Public Use Microdata Sample (PUMS) files are a set of untabulated records about individual and housing units. It is individual and household-level data, hence called microdata. PUMS are coming from ACS, but unlike typical pretabulated (summary) ACS data products, the Census Bureau produces PUMS untabulated so that data users can create their own custom tables. Summary products: tables and profiles available via American FactFinder (AFF) show pretabulated data for specific geographic area. PUMS files: population and housing unit records with individual response information such as age, income, marital status, education level, employment status. Users can later aggregate PUMS files into Region, Division, State, and Public Use Microdata Areas (PUMAs). PUMS files are accessible via: AFF FTP IPUMS-USA 42

43 6. PUMS 43

44 6. PUMS This way is desirable if we would like to get the entire U.S. data for both individual and house-level data. But, if we only want to get data for a state, there is another way which requires less data clean up. Click View (to the left of Download ) instead. 44

45 6. PUMS A. Click View instead, we will arrive at this page B. Suppose we want individual-level data for IL, we select Illinois Population Records and we will get a zip file named csv_pil.zip. For IL housing unit records, the file will be csv_hil.zip. For SAS format, the files would be either unix_pil.zip or unix.hil.zip. So, the zip file name format is f_rxx.zip, where: f is data format, csv or unix (SAS); r is record type, p for population and h for housing unit; xx is state abbreviation (in lower case). 45

46 6. PUMS Access PUMS data via FTP. For Yr ACS: Notes: Scroll down and you will see other data format, data record, and states. For other ACS, click parent directory (1). For naming guideline, click documentation for the naming convention (2). 46

47 6. PUMS Via IPUMS-USA ( Two important sections to get started: (1) Data section; and (2) Documentation section. It is free, but a user first needs to register and request access to get the most out of the website. Simply fill a form and submit it. Click IPUMS Registration under Data section (1). As a registered user, one can save the data extracts history, then revisit it later to: resubmit an extract or revise/update an extract (using different ACS sample, adding variables, select cases, or attach characteristics). Many useful resources in Documentation section (2). 47

48 6. PUMS Via IPUMS-USA ( 1. Login page 2. After login page: A. Make a new data extract; B. Visit data extract history to revise or resubmit a data extract. 48

49 6. PUMS Via IPUMS-USA ( A. Make a new data extract 49

50 6. PUMS Via IPUMS-USA ( A. Make a new data extract Select Variables Variables search can be done by Household or Person groups, alphabetical or a try & luck search. In this example, it is done by Person group, then Education category. Other categories include Demographic, Income, and Work categories. Then, a set of education variables is returned. Click a variable to get a detailed description. Codes (categorical values) are also given. Click a plus sign next to a variable to add the variable into the data cart. 50

51 6. PUMS Via IPUMS-USA ( B. Revise/resubmit a data extract Data extract history can be accessed from the main page (Left); OR through after-login page (Right) 51

52 6. PUMS Via IPUMS-USA ( To extract: In essence: 1. Downloaded files need to be decompressed, using a suggested software. See step 2 on the instruction. 2. Statistical software is needed to open and further process the files. 52

53 7. IECAM Experience IECAM s two primary uses of Census data 1. Searchable demographics: ACS,PEP 2. Risk factors: ACS, PUMS (via IPUMS-USA) Search page IECAM main page Risk Factors page 53

54 7. IECAM Experience Ingredients for the 2013 demographic release: o Yr ACS (ACS ) o PEP v.2013 for years 2013, 2012, 2011 Accessed via: o ACS files through American FactFinder o PEP files through cdc.gov website Notes: the Census Bureau itself does not release estimate with single year of age at county level. However, these estimates are provided to the National Center for Health Statistics. 54

55 7. IECAM Experience The ACS tables for the 2013 demographics release Table Number Table Name Universe Demographics B01001 SEX BY AGE Total population Population 0-5, 6-12, and population by race/ethnicity B09001 POPULATION UNDER 18 YEARS BY AGE Population under 18 years Population 0-5, 6-12 B01001A SEX BY AGE (WHITE ALONE) People who are White alone Population by race/ethnicity B01001B SEX BY AGE (BLACK OR AFRICAN AMERICAN ALONE) People who are Black or African American alone Population by race/ethnicity B01001C SEX BY AGE (AMERICAN INDIAN AND ALASKA NATIVE ALONE) People who are American Indian and Alaska Population by race/ethnicity Native alone B01001D SEX BY AGE (ASIAN ALONE) People who are Asian alone Population by race/ethnicity B01001E SEX BY AGE (NATIVE HAWAIIAN AND OTHER PACIFIC ISLANDER ALONE) People who are Native Hawaiian and Other Population by race/ethnicity Pacific Islander alone B01001H SEX BY AGE (WHITE ALONE, NOT HISPANIC OR LATINO) White alone, not Hispanic or Latino Population by race/ethnicity population B01001I SEX BY AGE (HISPANIC OR LATINO) People who are Hispanic or Latino Population by race/ethnicity B16002 HOUSEHOLD LANGUAGE BY HOUSEHOLD LIMITED ENGLISH SPEAKING STATUS Households Language B17024 AGE BY RATIO OF INCOME TO POVERTY LEVEL IN THE PAST 12 MONTHS Population for whom poverty status is Various Federal Poverty Levels (FPLs) determined B23008 AGE OF OWN CHILDREN UNDER 18 YEARS IN FAMILIES AND SUBFAMILIES BY LIVING ARRANGEMENTS BY EMPLOYMENT STATUS OF PARENTS Own children under 18 years in families and subfamilies Children across parents' working conditions Geographies selection: State, counties, townships, municipalities, 2010 ZCTAs, congressional districts, state senate districts, state house districts, elementary school districts, and unit school districts 55

56 7. IECAM Experience An example: retrieving poverty data via AFF The selection box will look like this (see the left chart). Scroll down, all desired geographies will be listed. Here is up to townships, a.k.a. county subdivision. Familiarity with some geographic terms in AFF will be helpful: Municipalities a.k.a. Place within State; State senate districts a.k.a. State legislative districts (upper); State house districts a.k.a. State legislative districts (lower). 56

57 7. IECAM Experience Applicable geographies in IECAM demographics release are red-highlighted. 57

58 7. IECAM Experience Ingredients for the risk factors o ACS datasets/tables o PUMS files o Other data as needed Accessed via: o ACS files through American FactFinder o PUMS files through IPUMS-USA website o Federal or state agencies (e.g., BLS, IDPH) 58

59 7. IECAM Experience An example: to estimate teen-mothers via IPUMS-USA (1) Extract set-up (2) Case selection Sample: 2013 ACS Red-highlighted variables are the ones we define to produce an estimate 59
