California's youth population dropped by more than 400,000 throughout the past 10 years to 8.9 million young people, attributed, in part, to a drop in immigrant inflows and the state’s lowest birth rate in history, Bloomberg reports, citing the latest Census data.

The big picture: The youth slump is a trend across the U.S., where 30 states noted a dip in the under-18 age group between 2010 and 2019, newly released data shows.

Meanwhile: At the other end of the spectrum, Texas's youth population rose from 6.9 million in 2010 to 7.4 million as of 2019.

  • The state has one of the highest birth rates in the country, and "strong in-migration from places like California and New York and rising immigration from Asia," per Bloomberg.

Why it matters: Changing demographics can impact a state's political leaning and economy, especially as the federal government prepares for the 2020 Census. California has never lost a House seat, but could this November given the population shifts, per Bloomberg.

The Supreme Court on Monday denied a request from Pennsylvania's Republican Party to shorten the deadlines for mail-in ballots in the state. Thanks to the court's 4-4 deadlock, ballots can be counted for several days after Election Day.

Why it matters: It's a major win for Democrats that could decide the fate of thousands of ballots in a crucial swing state that President Trump won in 2016. The court's decision may signal how it would deal with similar election-related litigation in other states.
