The state of New Jersey has a population of about 8.9 million and its area is about 8700 mi². What is the population density of
2 answers:
The population density is obtained by dividing the population by the area.
Here the population is given as 8.9 millions
1 miilion = 10,00,000
so 8.9 millions = 8.9 ×10,00,000= 8,900,000
The area of the State of New Jersey = 8700 miles².
Hence population density =
Rounding it off we get
Population density = 1023 people per square mile.
