Major U.S. cities with high tax burdens, including New York City, Boston, Los Angeles, and San Francisco, are experiencing significant population declines or stagnation, according to recent studies and Census data [1]. A Citizens Budget Commission (CBC) study found that New York City lost approximately 114,000 more domestic residents than it gained in 2025, reversing two years of marginal growth [1]. New York Governor Kathy Hochul has publicly expressed concern, warning that the erosion of the state's tax base threatens funding for social programs and highlighting competition from lower-tax states such as Texas, especially for Wall Street businesses [1].
Boston is also facing challenges in retaining young talent. The 2026 Young Residents Survey from the Greater Boston Chamber of Commerce Foundation revealed that 26% of residents aged 20 to 30 plan to leave the area within five years, with nearly half intending to exit Massachusetts entirely. High housing costs are cited as the primary reason for this out-migration. Over the past five years, Massachusetts has experienced a net loss of approximately 182,000 residents due to domestic out-migration, according to the Pioneer Institute [1].
On the West Coast, Los Angeles County saw the largest numeric population decline of any U.S. county, losing 53,421 residents between July 1, 2024, and July 1, 2025. Since 2020, the county's population has decreased from roughly 10 million to 9.7 million. San Francisco's population remains below pre-pandemic levels, despite growth in the artificial intelligence sector [1].
In contrast, the Southeast is experiencing robust population growth. The Census Bureau reported that many of the fastest-growing counties are now in Florida, Georgia, South Carolina, and North Carolina. South Carolina led the nation with a 1.5% population increase between July 2024 and July 2025, driven by a net influx of 66,622 domestic migrants [1].
CONCLUSION
High-tax cities across the U.S. continue to lose residents, threatening their tax bases and economic vitality, while Southeast states are attracting significant domestic migration. Policymakers in affected cities are voicing concern and may need to address tax and cost-of-living issues to stem the outflow. The ongoing population shifts could have lasting impacts on regional economies and public services.
