These data were created for the Oahu Metropolitan Planning Organization (OahuMPO) using the 2010 U.S. Decennial Census data to assess the spatial distribution of racial minorities and the American Community Survey (ACS) data to assess the distribution of people living in poverty. The “OMPO 2004 Environmental Justice in the OMPO Planning Process: Defining Environmental Justice Populations” (OahuMPO, 2004) report outlines the methodology used to determine EJ minority and poverty block groups using data from the 2000 Census. This methodology addresses the fact that the majority of the population in Hawai’i identifies as a minority race. Thsi methodology was applied to the 2010 Census data for race, and the 2009-2014 ACS data for poverty.
