Florida's Population Center Migrates through History

Throughout history Florida’s population has continuously repositioned itself.  At the time of the first census in 1830, Florida had only 34,730 people, concentrated primarily in the Panhandle region.  By 2010 the population had grown to 18,801,310 people, concentrated in the central and southern peninsula.  This study will track the movement of the geographic center of Florida’s population from 1830 to 2010.  This movement will be illustrated by calculating and mapping the centroid of Florida’s total population.

The changing pattern of Florida's population can be visualized with tables, graphs or maps. An alternative representation of the geographic change is a map that tracks the movement of the center point of the population through time. This is called the cen

Population forecasts for small areas (e.g., traffic analysis zones, school zone, neighborhoods, zip codes) often play an important role in public and private sector decision making.  They are essential in planning for future needs related to transportation, education, housing, emergency services, utilities, water resources, climate change, health care, local government planning, and many other goods and services.

County-level population projections don’t give enough detail for use in planning and decision making by local governments, utilities, transportation, schools, emergency services, or business/market studies. Geospatial models can meet this need.
