What Is the Most Populated State in the United States?
As of the 2025 population estimates, California remains the most populated state in the USA, followed by Texas and Florida.

Top 10 Most Populated States in the US (2025)
1. California – 39,431,263 (2025 est.)
California continues to hold the title of the most populated state in the United States. From the tech hubs of Silicon Valley to the entertainment capital of Los Angeles, California’s vast economy and desirable climate make it a magnet for residents.

2. Texas – 31,290,831 (2025 est.)
Texas has seen the most dramatic growth in recent years, rising from 29.1 million in 2020.

📈 Population Trends in the United States
Several trends emerge when analyzing the most populated states in the US.

💡 Why Population Matters
The population size of a state affects more than just its ranking. It determines the number of representatives it has in the U.S. House of Representatives, influences federal funding allocations, and shapes policy decisions at every level.
