This layer displays per capita personal income by county. This measure of income is calculated as the total personal income of the residents of an area divided by the population of the area. Per capita personal income is often used as an indicator of consumers’ purchasing power and of the economic well-being of the residents of an area. Information used in this map layer is acquired from the US Bureau of Economic Analysis Regional Economic Accounts: Economic Profile (CA30).
EPA Climate Change Indicators – Change in Snowfall
This indicator examines changes in total snowfall in the contiguous 48 United States. Indicator data are acquired from the EPA’s Climate Change Indicators in the United States, Fourth Edition, published in 2016.
Places of Worship, 2016
This layer displays locations of places of worship. Address-level data are acquired from the September 2016 IRS Exempt Organization Business Master File Extract (EO BMF) based on filing requirement code.
EPA Climate Change Indicators – Change in River Flooding
This indicator examines changes in the size and frequency of inland river flood events in the United States. Indicator data are acquired from the EPA’s Climate Change Indicators in the United States, Fourth Edition, published in 2016.
National Hydrography Dataset (Waterbody)
The National Hydrography Dataset (NHD) is used to portray surface water. The NHD represents the drainage network with features such as rivers, streams, canals, lakes, ponds, coastline, etc. The principal components of the NHD are:
- NHDFlowline: This is the fundamental flow network consisting predominantly of stream/river and artificial path vector features. It represents the spatial geometry, carries the attributes, models the water flow, and contains linear referencing measures for locating events on the network. Additional NHDFlowline features are canal/ditch, pipeline, connector, underground conduit, and coastline.
- NHDArea: This feature class contains many additional features of water polygons. One of the more important is the stream/river feature. It represents the aerial extent of the water in a wide stream/river with a basic set of attributes. They typically contain NHDFlowline artificial paths that are used to model the stream/river. Artificial path carries the critical attributes of the stream/river, whereas NHDArea represents the geometric extent.
- NHDWaterbody: Basic waterbodies such as lake/pond features are represented here. They portray the spatial geometry and the attributes of the feature. These water polygons may contain NHDFlowline artificial paths to allow the representation of water flow. Other NHDWaterbody features are swamp/marsh, reservoir, playa, estuary, and ice mass.
On-Time Graduation Rates, 2014-15
This layer displays information about the adjusted four-year cohort graduation rate for school-districts and counties in the United States.

Majority-Minority Schools
This layer displays the location of public schools where the majority (50% or more) of the student body is a minority race or ethnicity (American Indian, Asian, Black, Hispanic/Latino, Pacific Islander, or Multiple Race). This point-level data is acquired from the 2014-2015 National Center for Education Statistics (NCES) Common Core of Data (CCD).
Access to SNAP-Authorized Retailers
This layer displays the number and rate of SNAP-authorized retailers in each census tract and county. Locations of retailers are based on the December 22, 2017 USDA directory of SNAP-authorized retailers.
