It's a milestone moment for Westchester as new census data shows the county has reached a record high of more than 1 million residents.

Over the past several decades, the county has seen a consistent increase in its population. The 2020 census shows a steep jump from the last decade.

The county's 2019 census population estimated a population of 967,000. And by 2020, it grew by well over 37,000 residents.

The diversity of residents in the county has also grown in the last decade — alongside the rest of the U.S. population.

The U.S. Census Bureau released demographic data showing the multiracial population spiked to nearly 44 million in the 2020 count, which is from 9 million in 2010.

These numbers will be used to redraw the nation's political maps and shape how $1.5 trillion in annual spending is distributed.

Westchester says an accurate census count can bring billions of dollars in state and federal funding to the county's schools, infrastructure, hospitals and fire departments. "We often thought that we were undercounted for a number of years, but this proves the population has been growing in Westchester and I think it's a sign of Westchester's vitality," says Westchester County Executive George Latimer.

The numbers also show the city of Yonkers has moved up the charts as one of the most populated cities in New York — taking Rochester's former place as the state's third-largest city.
