Pima Association of Governments, with direction from its Population Technical Advisory Committee, prepares population estimates and projections for Pima County and its incorporated jurisdictions. As the region continues to experience rapid growth, accurate and reliable information is an important planning tool for decision makers in many fields.

The links in this section (at left) will provide you with more detailed population statistics from Census data and historical and current building activity.

Population estimates are based upon real data for a date that has passed, whereas population projections are based upon educated guesses about future conditions. Both estimates and projections take into account current economic, demographic and land use trends.
  
PAG develops a complete residential and employment projection every five years, and plans to develop an abbreviated residential projection every year.

Pima Association of Governments’ Population Technical Advisory Committee was established to ensure that public and private interests are informed and represented in the development of these numbers. Committee members help identify economic, employment and land use factors, and trends that are used to formulate population estimates and projections.
