The US State Closest to Hong Kong Population-wise

As of the end of 2025, Hong Kong boasted a population of 7,510,800 inhabitants. To put that figure into an American context, the population of Hong Kong is most similar to that of the state of Arizona, which had a population of 7,600,000.

However, the comparison ends here. Although the total populations of both territories are very similar, the living conditions are dramatically different. Arizona is a landlocked state, with its water area representing 0.3% of the total area. Hong Kong, on the other hand, consists of 263 islands and is surrounded by the sea, with its water area accounting for 59.7% of its total area.

The state of Arizona covers a land area of 294,207 square kilometers (113,594 square miles) making it the sixth-largest U.S. state by land area. Hong Kong, on the other hand, covers a land area of 1,114.35 square kilometers (430.25 square miles). That is 264 times smaller than Arizona.

In other words, the population density reaches 24 inhabitants per square kilometer (63 inhabitants per square mile), in Arizona; compared to an astonishing 6,800 inhabitants per square kilometer (17,614 inhabitants per square mile), in Hong Kong. That is, Hong Kong is 283 times more densely populated than the state of Arizona.
