The U.S. Census Bureau often revises previous estimates. Therefore, figures presented here may be different from figures presented elsewhere.

A family includes a householder and one or more people living in the same household who are related to the householder by birth, marriage, or adoption. All people in a household who are related to the householder are regarded as members of his or her family. According to the ACS subject definitions guide ( a household contains only one family in the published tabulations.

The 2011-2015 ACS data release marked the seventh time that 5-year estimates were released for all areas. The ACS 2011-2015 data were collected during calendar years 2011, 2012, 2013, 2014, and 2015.

The 5-year ACS estimates represent the average characteristics over the 5-year period of time, and therefore are less current than 1-year and 3-yearACS estimates. However, these estimates are more reliable because they are based on a larger sample size and provide data for counties with populations less than 20,000. The 3-year estimates are available for geographic areas with populations of 20,000 or greater, while 1-year estimates are only published for populations of 65,000 or greater.
