GRID ANALYSIS


Grid Query

You can perform complex queries on a single grid or on multiple grids to determine where two or more variables are coincident. In this example, you can analyze the relationship between locations where children have elevated blood lead levels and where average family income is very low.

Elevated Blood Lead Levels
Lead Levels over 10 micrograms per deciliter
Average Family Income
Income under $15,000
