In addition, the survey found about 225 special intra-municipal districts and about a score of regional and inter-municipal districts and commissions. "This is the New Jersey patchwork . . . ," says the Princeton report. The terms "city," "town," "borough" and "township" are entirely meaningless as far as classification by size or area is concerned. The largest city is Newark, with nearly half a million residents; the smallest is Corbin City, with a population of 256. The largest township is North Bergen, population 40,714; the smallest is Pahaquarry, population 80. North Cape May and South Cape May, with populations of 5 and 6, are the smallest boroughs.

Patchwork government is expensive, the Princeton survey declares. Citing the police organization, a 1936 bulletin says:

There are 350 separate and independent police departments in New Jersey, of which 127 are in the five counties covering a scant 700 square miles of northeastern New Jersey. Nowhere else in the United States is there such a concentration of separate police agencies in so small an area.

This goes far to explain the fact that costs of New Jersey police protection are not only the highest in the United States for cities of the corresponding size groups, but in some cases they are nearly twice as high.

At the entrance to the Holland tunnel a citizen can be arrested by at least five different sets of police officers, for violation of several sets of traffic laws.
