  • 2016 ACS 1-year estimates
  • 2010 Census
  • 2000 Census

To learn more about comparing the 2013-2017 ACS 5-year estimates with the 2008-2012 ACS 5-year estimates visit the 5-year to 5-year Comparison Guide page.

If you would like to compare the 2017 ACS 1-year with estimates with ACS estimates prior to the 2016 ACS, please refer to the year-by-year comparison guidance throughout the entire time span. For example, to compare the 2017 ACS 1-year estimates with the 2015 ACS 1-year estimates, please reference:

Compare

2017 ACS with 2010 Census (Age)

Compare

2017 ACS with Census 2000 (Age)

Compare with Caution

The entire population continually ages into older age groups over time and babies fill in the youngest age group. So, the population of a certain age is made up of a completely different group of people from one time period to the next. Since populations occasionally experience booms/increases (for example, the postwar Baby Boom from 1946-1964) and busts/decreases in births, deaths, or migration, one should not necessarily expect that the population in an age group in Census 2000 should be similar in size or proportion to the population in the same age group in different data year(s). For example, Baby Boomers were ages 36 to 54 in Census 2000 while they were ages 53 to 71 in the 2017 ACS 1-year, and between ages 49 to 71 in the 2013-2017 5-year period. So, the age groups 55 to 59, 60 to 64, and 65 to 69 would show a considerable increase in population when comparing Census 2000 data with the single year or multiyear ACS data.

Compare with Caution

Differences between the 2017 ACS and Census 2000 may be the result of demographic changes and/or differences in question wording (the ACS question on race was revised in 2008 to make it consistent with the 2010 Census race question), race reporting, or methodological differences in the population estimates used as ACS controls.

The ACS question on Hispanic origin was revised in 2008 to make it consistent with the 2010 Census Hispanic origin question. Any change, compared with Census 2000, may be due to demographic changes, questionnaire changes, differences in ACS population controls, and/or methodological differences in the population estimates.

2017 ACS with Census 2000 (Ancestry)

Compare

Ancestry is the only item for which a "not reported" category is published since missing ancestries are never assigned or allocated. The extent of missing ancestry answers was higher in Census 2000 than in the ACS. The difference in the level of response may contribute to the difference in the two distributions.

For data year 2012 and subsequent years, note that the topmost year of entry category in many tables was changed from "2000 or later" to "2010 or later." For data year 2011 and earlier, note that Census 2000 represents data collected as of April 1, 2000 and thus the "2000" year of entry category accounts for the first quarter (Jan-Mar) in 2000 only. The ACS represents data collected throughout the entire year and thus the "2000" year of entry category accounts for the entire year of 2000.

The ACS used a joint relationship/marital status edit and Census 2000 did not--these edits are used to determine categories of family types. Also, Census 2000 provided more response categories because of a write-in option that was not used in the ACS.

The ACS has two separate categories for completing high school - "Regular high school diploma" and "GED or alternative credential." Census 2000 has only one category for completing high school - "HIGH SCHOOL GRADUATE - high school diploma or equivalent (for example: GED)." As a result, users may see differences in distributions when comparing Census 2000 to ACS data from 2008 and later years.

2017 ACS 1-Year with 2016 ACS 1-Year (Poverty Status of Families and People in Families)

Compare with Caution

As ACS data are collected every month of the year, adjacent years will have some reference months in common. Hence, comparing the 2017 ACS 1-year with the 2016 ACS 1-year estimates is not an exact comparison of the economic conditions in 2017 with those in 2016.

2017 ACS with Census 2000 (Poverty Status of Families and People in Families)

Compare with Caution

The ACS collects data throughout the year on an on-going, monthly basis and asks for a respondent's income over the "past 12 months." Census 2000, however, collected the income data for a fixed period of time -- "during 1999" (the last calendar year). For example, the 2017 ACS 1-year data reflect incomes over 2016-2017, and the 2013-2017 ACS 5-year data reflect incomes over 2012-2017. In a comparison study between Census 2000 income data and the 2000 ACS, income collected in Census 2000 was found to be about 4 percent higher than that in the 2000 ACS.

2017 ACS with Census 2000 (Period of Military Service)

Compare

Since Census 2000, the period of military service categories on the ACS questionnaire were updated to: 1) include the most recent period "September 2001 or later;" 2) update the Korean War and World War II dates to match the official dates as listed in US Code, Title 38; and 3) collapse peacetime periods between the Vietnam era and the 1990 Gulf War. While the response categories differ slightly from those in Census 2000, data from the two questions can still be compared to one another.

2017 ACS with Census 2000 (Veteran Status)

Compare with Caution

The ACS has two separate questions for veteran status and period of military service, whereas in Census 2000, both were asked in a two part question. The veteran status question itself remained similar until 2013. In 2013, the italicized instruction to the question was removed and the response categories were revised and rearranged. Users should use caution when comparing 2017 ACS data with Census 2000.

2017 ACS with Census 2000 (Employment Status)

Compare with Caution

The reference periods are different due to year-round ACS data collection. The ACS reference period is the week prior to the respondent completing the interview, or the field representative conducting the interview. Because questionnaires are mailed-out and field interviews are conducted throughout the year, there is a revolving reference period. For Census 2000, the reference period was the week prior to Census Day (April 1, 2000). The Census 2000 Summary File 3 (SF3) labor force data for some places where colleges are located appear to overstate the estimates of people in the labor force, the unemployed, and the percent unemployed because of data capture errors.

2017 ACS with Census 2000 (Class of Worker)

Compare with Caution

The 2017 ACS Industry by Class of Worker tables combine "Unpaid family workers" with "Self-employed in own not incorporated business workers." The Census 2000 tables use different tabulation categories than the ACS. Also, the Census 2000 tables did not include the "full-time, year-round" population and there were no median earnings Class of Worker tables. Thus, comparisons cannot be made for this population or characteristic.

Compare with Caution

The total group quarters (GQ) population in the ACS may not be comparable with the 2010 Census.  The ACS does not include all the GQ types that are found in the decennial census. For instance, domestic violence shelters, soup kitchens, regularly scheduled mobile food vans, and shelters for victims of natural disasters. The exclusion of these GQ types from the ACS may result in a small bias in some ACS estimates to the extent that the excluded population is different from the included population.

2017 ACS with Census 2000 (Group Quarters Population)

Compare with Caution

The total group quarters (GQ) population in the ACS may not be comparable with Census 2000 because there are some Census 2000 GQ types that were out of scope in the ACS such as domestic violence shelters and soup kitchens. Also, there are some Census 2000 GQ type categories that are no longer valid (e.g., residential care facility providing "Protective Oversight," hospitals/wards for the chronically ill, and hospitals/wards for drug/alcohol abuse). The exclusion of these GQ types from the ACS may result in a small bias in some ACS estimates to the extent that the excluded population is different from the included population.
