From April 2020 to July 2021, the city lost nearly 7% of its population, going from 873,965 to 815,201 residents — the lowest number since 2010. Among those age 25 to 29 who identified as female, white and non-Hispanic, the population dropped by 26%. White men of the age group saw nearly the exact same decline.

The data shows that young people in general were more likely to leave the city. The city lost about 20% of all residents age 25 to 29 over this time and 15% of those 20 to 24. The chart shows the decline for every demographic combination provided by the census, which used data sources including IRS tax returns, Medicare enrollment and Social Security numbers to estimate the detailed population changes.
