A few analyses of household vehicle counts:
Data comes from the Census Data API (for NJ) and censusreporter.org (for Hudson County).
Two notable plots / observations:
In most of the state, ≈80% of the vehicles come from multi-vehicle households! Hudson County is an exception, where it's ≈50%.
There is a huge opportunity for helping families need one fewer car. Replacing one car with an ebike is a popular move, provides the house with a cheaper, cleaner, healthier, and more fun vehicle for many trips.
In Hudson County cities (other than Hoboken), 50-75% of the total vehicles come from multi-vehicle households.
