Recent census data reveals a notable slowdown in population growth across the United States, especially affecting major metro areas. The decline in immigration appears to be a primary factor contributing to this trend, with areas along the southern border experiencing the steepest drops. Counties like Los Angeles, Miami, and San Diego have shown population reductions, while some Texas suburbs continue to grow, albeit at a slower rate. New findings also indicate that greater regions, such as Western New York, are losing residents as deaths exceed births. This shift in demographics raises questions about the long-term implications for urban development and economic vitality across the nation.
