As more people move into the Chesapeake Bay region, development has turned forests, farms and other landscapes into subdivisions, shopping centers and parking lots. As more people have moved in, the health of the Bay has, inevitably, declined.
Over the past twenty-five years, NumbersUSA has published numerous scientific reports on the causes and consequences of sprawl in the United States. Our most recent study quantifies ecological decline in the Chesapeake Bay and its watershed over the past three decades. Looking forward, we explore a path toward ecological sustainability centered on stabilizing the region’s population through reduced immigration.

Despite half a century of efforts to improve water quality and restore fisheries in America’s Chesapeake Bay, its ecological health continues to decline. A new study from NumbersUSA quantifies this ecological decline within the Chesapeake Bay watershed, explores its causes, and discusses possible futures.

The HUD Report: Immigration and “Worst Case Housing Needs” In December 2025, the U.S. Department … Continued
Road salt causes long-term water contamination. Mass immigration expands roads and salt use. Population growth makes the damage unavoidable.
The border is secure and illegal migration is down. So, do we still need to be concerned about immigration? The answer is an emphatic yes.
For decades after the Clean Air Act (1970), new emission standards, cleaner fuels and technological innovations brought steady air quality improvements to America’s metro regions. But those gains have since stalled, as population growth, with its traffic expansion and rising energy demands, overwhelms the benefits of air pollution controls.
Politicians across the political spectrum agree that America has a housing crisis. Home prices and rents have surged beyond what many households can reasonably afford.
While business journalists and housing experts tend to focus on supply, the demand side of the equation is equally important in determining housing prices. When the number of families grows faster than the number of housing units, competition for existing housing increases and prices rise. This has happened in many parts of the country over the past four years, due to immigration-driven population growth.
