American Community Survey 2018
  -- 1-year estimates -- areas published

The 2018 American Community Survey (ACS 2018 main) 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. Access the ACS 2018 data through the ProximityOne Data Service tools.

The ACS 1-year estimates are tabulated for areas having 65,000 population or more. These areas are a small part of the total set of tabulation areas (all geographies) for which the 5-year estimates are produced. See more about the 1-year versus 5-year estimates below.

This section provides an interactive table that includes a list of all ACS 2018 1-year tabulation areas. Tabulation areas are produced for several types of geography or summary levels. Summary levels, associated names and ACS 2018 tabulation areas counts are shown in the following scroll 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 2018 (December 2019) 5-year estimates;
    - ACS 2018 5-year estimates are centric to 2016.
