D. New York
Answer (2)
Identify the population density for each city.
Compare the population densities.
Determine that Karachi has the highest population density.
Conclude that K a r a c hi has the largest number of people in the smallest amount of space.
Explanation
Understanding the Problem We are given a table with population and population density for four cities: Delhi, Manila, Karachi, and New York. The question asks which city has the largest number of people in the smallest amount of space, which is equivalent to finding the city with the highest population density.
Listing Population Densities The population densities for each city are as follows:
Delhi: 30,400 people per sq mi
Manila: 38,300 people per sq mi
Karachi: 67,300 people per sq mi
New York: 4,600 people per sq mi
Comparing Densities Comparing the population densities, we can see that Karachi has the highest population density at 67,300 people per sq mi.
Conclusion Therefore, Karachi has the largest number of people in the smallest amount of space.
Examples
Understanding population density helps urban planners make informed decisions about resource allocation, infrastructure development, and public services. For example, knowing the population density of a city helps in planning the number of schools, hospitals, and transportation systems needed to support the population. It also helps in identifying areas that may be overcrowded and require additional resources or infrastructure.
Karachi has the highest population density among the listed cities, with approximately 67,300 people per square mile, making it the city with the largest number of people in the smallest amount of space. The other cities, such as Manila and Delhi, have significantly lower population densities. Therefore, the answer is Karachi.
