Decennial Census

The Decennial Census is conducted every 10 years by the U.S. Census Bureau. It is a count of everyone residing in the United States on the census date of April 1st. The 2010 Census was the last decennial census taken.

In 2010, there were 10 questions on the form which included key demographic information such as gender, age, race, household relationship and whether the housing unit was rented or owned. Detailed socioeconomic data was no longer collected and is now found in the Census Bureau’s annual American Community Survey. Data from the 2010 Census is available from the national level down to the block level.

A good way to start your data search for 2010 Census data is to decide what geographic area you are interested in. Local level data (below the county level) are frequently requested and the geographical level of census tract is recommended. Census tracts cover every part of our state. The next step is to obtain the data that you need. The demographic profiles will provide some basic information from this census. A series of Hawaii State Data Center reports found on the “DBEDT Product Page” may also be a good source of 2010 data that you need.
