Source Description

The Economic Research Service (ERS) by the USDA anticipates trends and emerging issues in agriculture, food, the environment, and rural America and to conduct high-quality, objective economic research to inform and enhance public and private decision making.

Methodology

This indicator reports the topographic variation, or “ruggedness,” for census tracts across 50 States and Washington, DC. The Area Ruggedness Scale (ARS) has six categories based on the changes in elevation for all terrain and classifies census tracts as: (1) level; (2) nearly level; (3) slightly rugged; (4) moderately rugged; (5) highly rugged; and (6) extremely rugged.

Terrain Ruggedness Index (TRI): A grid-cell-level measure of elevation change between a grid cell and its adjacent grid cells. TRIs were used as a building block to create the categorical scales.
