One face of immigration in America

• A larger share of the U.S. population is foreign-born now than at any time since 1910. In recent years, the trend is not so much with Latin Americans crossing the border, but with educated people from Asia obtaining visas.

Many of those immigrants came through family reunification policies that the Trump administration hopes to scale back. Some experts predict that the number of immigrants granted permanent legal residency in this fiscal year, which ends Sept. 30, will show a rare decline.

• Looking to 2020: Michael Bloomberg, the former mayor of New York City, is considering running for president as a Democrat. But he has sharp disagreements with the party on issues including bank regulation and stop-and-frisk police tactics.

Another source of subway delays

• New York City’s efforts to pull its transit system from crisis have been hampered by ancient signaling systems, creaky trains and, increasingly, by people venturing onto the tracks.

There were nearly 900 incidents last year in which someone was on the tracks or hit by a train after getting too close while on the platform. This year, that number is set to rise.

• The cause: Subway officials aren’t sure, but there’s speculation it may be in part because of the many homeless people inside the system or the number of smartphones that fall onto the tracks.
