Washington • Justice Elena Kagan’s father was 3 years old when the census taker came to the family’s apartment on Ocean Parkway in Brooklyn, New York, on April 10, 1930.
Robert Kagan was initially wrongly listed as an "alien," though he was a native-born New Yorker. The entry about his citizenship status appears to have been crossed out on the census form.
Vast changes in America and technology have dramatically altered the way the census is conducted. But the accuracy of the once-a-decade population count is at the heart of the Supreme Court case over the Trump administration’s effort to add a citizenship question to the 2020 census.
