Combined Statistical Areas

Introduction

A Combined Statistical Area (CSA) is a geographic region that combines two or more adjacent Core Based Statistical Areas (CBSAs) with significant economic and social ties, based on commuting patterns. CSAs are defined by the US Office of Management and Budget (OMB) and are used for demographic and economic analysis, while the individual CBSAs retain their own distinct identities within the larger CSA.

The map and table below give geographic data on the nine CSAs that lie completely or partially in Alabama. The land and water areas are given in square miles.
