The physical environment in LaSalle County is undergoing constant change even if that change is slow and not obvious. The socioeconomic state of the County is also dynamic. Population, income, and employment, and particularly the spatial distribution of these attributes, all play a role in the development of the County.
The population of LaSalle County is projected by the Illinois Department of Commerce and Economic Opportunity to increase from a historical two percent per decade to four percent per decade, reaching about 141,615 people by 2030. We’re guiding residential developments into areas that can most effectively and economically provide urban services and amenities.
