According to the most recent population estimates released by the U.S. Census Bureau, New Jersey’s population has increased from 8,414,360 in 2000 to 8,682,661 as of last year. That would man legislative districts would increase in size, ideally, from 210,359 to 217,066. State law requires legislative districts to be +/- 10% of that number – a range of 195,359 to 238,773.
If New Jersey loses one congressional seat, as expected, House districts would go from 647,258 to 723,555. All House districts are expected to be identical in size.
