American Community Survey 2018
-- ACS 2018 5-year estimates
-- annually updated demographic-economic data to the block group level

Essential data to assess where we are, how things have changed and how things might change in the future down to the sub-neighborhood level. The American Community Survey (ACS) is a nationwide survey designed to provide annually updated demographic-economic data for national and sub-national geography. ACS provides a wide range of important data about people and housing for every community across the nation. The results are used by everyone from planners to retailers to homebuilders and issue stakeholders like you. ACS is a primary source of local data for most of the 40 topics it covers, such as income, education, occupation, language and housing. ProximityOne uses ACS data to develop current estimates on these topics and 5-year projections.

This section is focused on ACS 2018 data access, integration and use. A similar set of data are produced/released annually. It is updated periodically. Register to receive updates. See related ACS 2017 5-year section.

Further Drill-down; Houston, TX inner beltway area ... goto top
  patterns of economic prosperity by neighborhood; census tract
Similar to the above view, the following graphic shows patterns of ACS 2018 5-year estimates of median family income ($MFI) by census tract with zoom-in to Houston, TX inner beltway area. Colors assigned to income intervals are shown in the inset legend. Tracts are labeled with $MFI. Click graphic for larger view. Expand browser window to full screen for best quality view. Larger view shows tracts labeled with $MFI (yellow label) and the census tract code (white label). Some tracts show the top coded value of $250,001, indicating the value is $250,000 or more. In this view, all tracts are within Harris County, TX (48201) so the 6 character tract code uniquely identifies the tract.

Tip of the Iceberg; Illustrating More Detailed Data in Profile/Tabular Form ... goto top
Toward the center of the larger map shown for the Houston drill-down, above, note the two adjacent higher and lower $MFI tracts (100000 and 410100, or sometimes shown as 1000.00 and 4191.00). The $MFI values are item E086 shown in the economic profiles for these tracts accessed by clicking the links below. Using these organized profiles, it is easy to view related attributes of these tracts and how they are similar or different. Even with the approximate 522 subject matter items for the profiles, this set of subject matter items remains the "tip of the iceberg". More detailed data contained in tables (see table shells) further down in this section.

Using ACS Data; ACS 1-Year versus ACS 5-Year Data .. top

While ACS 1-year estimates are suitable for time-series analyses, the ACS 5-year estimates are not the same as annual demographic-economic estimates and may not be suitable for annual time series analyses.

Advantages of using the 5-year estimates
  • the data are available for all census tracts and ZIP code areas.
  • the data are available for all cities/places, counties and school districts irrespective of size.
Disadvantages of using the 5-year estimates
  • the data are older than the 1-year estimates.
  • the data are for a 5-year period rather than one year.
  • additional cautions in comparing estimates over time (see below).

Advantages of using the 1-year estimates
  • the data are more recent than the 5-year estimates.
  • the data are generally more accurate than the 5-year estimates.
Disadvantages of using the 5-year estimates
  • the data are not available for census tracts and ZIP code areas.
  • the data are available for only areas of 65,000 population and over.
  • the margin of error (MOE) of the estimate is normally larger that for the 5-year estimates.

Additional cautions in comparing estimates over time
  • ACS 2012 5 year estimates are based on survey respondent data for the years 2008 through 2012.
  • ACS 2013 5 year estimates are based on survey respondent data for the years 2009 through 2013.
  • ACS 2014 5 year estimates are based on survey respondent data for the years 2010 through 2014.
  • ACS 2015 5 year estimates are based on survey respondent data for the years 2011 through 2015.
  • ACS 2016 5 year estimates are based on survey respondent data for the years 2012 through 2016.
  • ACS 2017 5 year estimates are based on survey respondent data for the years 2013 through 2017.
  • ACS 2018 5 year estimates are based on survey respondent data for the years 2014 through 2018.
  • The ACS 2012 5 year data & ACS 2013 5 year data
      are based on the same respondent data for the four years 2009 through 2012.
  • The ACS 2013 5 year estimates drop 2008 respondents and add 2013 respondents.
  • The ACS 2014 5 year estimates drop 2009 respondents and add 2014 respondents.
  • The ACS 2015 5 year estimates drop 2010 respondents and add 2015 respondents.
  • The ACS 2016 5 year estimates drop 2011 respondents and add 2016 respondents.
  • The ACS 2017 5 year estimates drop 2012 respondents and add 2017 respondents.
  • The ACS 2018 5 year estimates drop 2013 respondents and add 2018 respondents.
  • While 5-year estimates are independently developed annually,
      they include demographic-economic characteristics for some of the same respondents.

Other considerations
  • Are the needed subject matter available from Census 2010?
    - ACS more detailed demographic-economic data (like income) may not be a plus.
  • Census 2010 provides more accurate data than ACS estimates.
  • Often there are more detailed age (and other) breakouts for subject matter in Census 2010 compared to ACS.
  • The most recent ACS-sourced small area data are from ACS 2017 (December 2018) 5-year estimates;
    - ACS 2017 5-year estimates are centric to 2015.
