Local communities depend on information from the American Community Survey (ACS), as well as the 2020 Census, to decide where schools, highways, hospitals, and other important services are needed. The data collected through the ACS and the Census help determine how to distribute more than $675 billion of Federal funding each year….

- 4. 7/21/2021 4 American Community Survey/2020 Census American Community Survey • Conducted every month and year • Sent to a SAMPLE of addresses (about 3.5 million per year) in the United States, District of Columbia, and Puerto Rico • Asks questions about topics not on the 2020 Census, such as education, employment, and transportation • Provides current information about communities every year Decennial/2020 Census • Conducted every 10 Years • Counts every person living in the U.S., District of Columbia and the five U.S. Territories • Shorter list of questions, such as age, sex, race, and owner/renter status • Provides an official count of the nation’s population 7 ACS Features • Surveys a sample of 3.5 million addresses per year and informs Federal government spending of over $675 billion • Covers over 40 topics, supports over 300 evidence-based Federal government uses, and produces 11 billion estimates each year • Three key annual data releases • 1-year Estimates (areas w/ population of 65,000+) • 1-year Supplemental Estimates (areas w/ population of 20,000+) • 5-year Estimates (all areas) Ideal for analyzing data for small population groups 8 7 8
- 5. 7/21/2021 5 ACS Content 9 ACS Dataset Focus 5-Year Estimates • Describe the characteristics over a specific period, not a single point in time • Data are pooled across 60 months, weighted to produce estimates, and controlled for age, sex, race, and Hispanic origin • 5-year estimates are NOT an average of 1-year estimates • Estimates are based on geographic boundaries (“vintages”) as of the last year in the 5-year period • Dollar-value estimates are inflation adjusted to the most recent year for the period 10 9 10
- 6. 7/21/2021 6 11 Comparing 5-Year Estimates • Only compare non-overlapping time periods • 2015-2019 • 2010-2014 • Only compare 1-year estimates to 1-year and 5-year estimates to 5-year • Compare across geographies and subpopulations • Compare percentages, means, medians and rates instead of totals whenever possible 12 Margin of Error • It is very important to consider the margin of error (MOE). The ACS publishes them as a part of most data tables. • MOE describes the precision of an ACS estimate at a given level of confidence. The confidence level associated with the MOE indicates the likelihood that the ACS sample estimate is within a certain range of the population value. • MOEs for published ACS estimates are provided at a 90 percent confidence level. • A higher margin of error in statistics indicates less likelihood of relying on the results of a survey or poll, i.e., the confidence on the results will be lower to represent a population. 11 12
