Census and Statistics
One of the main ways to locate statistical information is through American FactFinder, the Census Bureau’s website for data retrieval. The Census Bureau collects information in a variety of surveys and then provides this information to the survey sponsor. The Bureau of Justice Statistics, The Bureau of Labor Statistics, the Bureau of Transportation Statistics, the Department of Housing and Urban Development, the National Center for Education Statistics, the National Center for Health Statistics, the National Science Foundation, and the Social Security Administration are among the sponsors for which the Census Bureau collects data.
From the Census Bureau site you can retrieve quick facts, updates about census releases, and explanations about the data the Census Bureau collects.
For the latest news releases and statements the U.S. Census Bureau, choose Information For…Media (Newsroom). Choose Facts for Features on the left-side menu of the Newsroom page, to find statistics for upcoming holidays, commemorative celebrations and months.
For various reports, tables, and clarifying information on how data is collected on different populations, click on the Browse by Topic tab then choose Population and the group you’d like to explore.
QuickFacts provides statistics for all states and counties, and for cities and towns with a population of 5,000 or more. This is a good place to look if you need basic information such as total population, homeownership rates, median income, and population changes for a particular area. Select the desired state from the drop down menu in the Quick Facts section in the center of the page.
In order to make Bay Area statistics more accessible, librarians at the MTC (Metropolitan Transportation Commission) library and ABAG (Association of Bay Area Governments) created this website specifically for Bay Area data from 1860 to the present. Similar to the State and County Quick Facts, this site provides data summaries for population, households, racial/ethnic makeup, income and poverty, employment, and transportation for cities, counties, and census tracts and blocks within the San Francisco Bay Area. It also includes links to national census data from as early as 1790.
This is the Census Bureau’s primary website for retrieving recent census data and replaced American FactFinder as of June 2019. Data from the two recent censuses 2000 and 2010 can be accessed as well as data from the American Community Surveys, which took the place of the long census form and contain detailed information about communities. The 1-year survey provides annual estimates for geographic areas with populations of 65,000 or more, the 3-year survey provides estimates for geographic areas with populations of 20,000 and more, while the 5-year survey covers geographic areas with populations less than 20,000. It is important to remember that these surveys provide estimates only. The tables will give margins of error, which you should factor into your results.

The Statistical Abstract of the United States contains social, political, and economic statistics for the United States. Most of the data in the Statistical Abstract is national, but there are some tables, such as population, representing data from metropolitan areas.
Until 2012, The Statistical Abstract was produced by the U.S. Census Bureau’s Statistical Compendium Program and was distributed to depository libraries and available in online format free-of-charge. Due to budget cuts, the Statistical Compendium Program was abolished in 2012. That same year Bernan Press began publishing The Statistical Abstract. Oakland Public Library has print copies from Bernan Press beginning in 2013 but does purchase online access. Online data from 1878-2012 will remain available on the Census Bureau’s website at the URL listed above.
