This market predicts the annual US population growth rate for 2025.

According to Census Bureau data, the US population grew by nearly 1.0% between 2023 and 2024, the highest growth rate since before the pandemic. For January 2025, the Census Bureau projected a growth rate of 0.78% from the previous year.

However, the Congressional Budget Office (CBO) has projected slower growth, with an average annual rate of just 0.2% over the next 30 years—less than a quarter of the rate recorded between 1975 and 2024. For the 2025-2035 period specifically, CBO projects an average growth rate of 0.4% per year.

Recent immigration policy changes and declining fertility rates could impact the 2025 growth rate.

Resolution Criteria: This market will resolve based on the official US population growth rate for calendar year 2025 (or the closest period approximating it) as reported by the US Census Bureau. If the Census Bureau reports multiple growth rates (e.g., for different time periods), the one most closely corresponding to the full calendar year 2025 will be used.
