In NJ it is. Jersey City, along with Newark, is considered the most developed in NJ.
In the US, not sure. I believe it is one of the most diverse.

Yes. Jersey City is the most "cosmopolitan" city in the US with neighborhoods of immigrants representing over 90 different nations. It is also the most "vertical" major city with 86% of its population living in multifamily housing. It was ranked the 17th largest city in the US in the year 1900, and 72nd largest in the year 2000, according to the US Census Bureau. Of the 100 largest cities in the US, it is the smallest in land area, but 2nd only to New York City in population density.
It depends what you mean by major city, but Jersey City, indeed, is a big city. Being in close proximity of New York City, has provided Jersey City with certain advantages (and disadvantages too), in terms of increasing concentration of companies, upmarket condominiums, bars and restaurants. The local economy is dependent on folks who work in NYC and live in Jersey City.
