Income from Transfer Payments, 2013
Layer displays information about personal income from transfer payments from the Bureau of Economic Analysis (BEA) Local Area Personal Income data series. In personal income, transfer receipts are benefits received by persons for which no current services are performed. Additional attributes include transfer benefits per capita, and percent change in benefits between 2009 and 2013.
Farm to School Participation by School District
This layer displays Farm to School participation based on responses to the 2013 Farm to School Census. Participation data refer primarily to activities occurring during the 2011-12 school year.
Locations of SNAP-Authorized Retailers
This layer displays the locations of SNAP authorized retailers across the US. Data has been updated to reflect stores accepting SNAP as of May 15, 2016.
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 May 15, 2016 USDA directory of SNAP-authorized retailers.
Access to Farmer’s Markets
This layer displays the percentage of each county’s population (or low income population) living near a farmer’s market (defined as within a 3 mile radius in urban areas and a 10 mile radius in urban areas). Data have been updated to reflect farmers markets from the May 2016 version of the USDA Local Food Directories database.
STD Incidence / HIV Prevalence by County
Layers display information about new incidence of sexually transmitted infections, and the prevalence of HIV / AIDS.
SNAP Recipients by County, 2013
This layer displays the percentage of population receiving SNAP benefits by county. Data are from the US Census Bureau 2014 Small Area Income and Poverty Estimates (SAIPE) dataset, released December 2015.
National Hydrography Dataset (Area)
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.
