Which conclusion does this table support?
| City and World Rank | Population | Pop. Density (people per sq mi) |
| :------------------- | :--------- | :------------------------------- |
| 4. Delhi (India) | 22,826,000 | 30,400 |
| 6. Manila (Philippines) | 21,241,000 | 38,300 |
| 7. Karachi (Pakistan) | 20,877,000 | 67,300 |
| 8. New York (US) | 20,673,000 | 4,600 |
A. The land areas of Karachi and New York must be very similar in size.
B. The population of Manila is greater than the population of New York.
C. New York has a smaller land area than Delhi or Manila.
D. New York has a larger land area than Delhi or Manila.
Answer (2)
Calculate land area for each city using: Land Area = Population Density Population .
Find that Delhi's land area ≈ 750.86 sq mi, Manila's ≈ 554.60 sq mi, Karachi's ≈ 310.21 sq mi, and New York's ≈ 4494.13 sq mi.
Compare populations: Manila (21,241,000) > New York (20,673,000).
Conclude: The table supports that Manila's population is greater than New York's. The population of Manila is greater than the population of New York.
Explanation
Understanding the Problem We are given a table with population and population density for four cities: Delhi, Manila, Karachi, and New York. We need to determine which conclusion is supported by the data.
Calculating Land Areas To determine the land area of each city, we will use the formula: Land Area = Population / Population Density. We will calculate the land area for each city using the given data.
Delhi's Land Area For Delhi: Population = 22,826,000 Population Density = 30,400 people per sq mi Land Area = 22,826,000 / 30,400 = 750.86 sq mi (approximately)
Manila's Land Area For Manila: Population = 21,241,000 Population Density = 38,300 people per sq mi Land Area = 21,241,000 / 38,300 = 554.60 sq mi (approximately)
Karachi's Land Area For Karachi: Population = 20,877,000 Population Density = 67,300 people per sq mi Land Area = 20,877,000 / 67,300 = 310.21 sq mi (approximately)
New York's Land Area For New York: Population = 20,673,000 Population Density = 4,600 people per sq mi Land Area = 20,673,000 / 4,600 = 4494.13 sq mi (approximately)
Analyzing the Conclusions Now, let's analyze the given conclusions:
The land areas of Karachi and New York must be very similar in size. Karachi's land area is approximately 310.21 sq mi, and New York's land area is approximately 4494.13 sq mi. These areas are not similar.
The population of Manila is greater than the population of New York. Manila's population is 21,241,000, and New York's population is 20,673,000. This statement is true.
New York has a smaller land area than Delhi or Manila. New York's land area is approximately 4494.13 sq mi, Delhi's land area is approximately 750.86 sq mi, and Manila's land area is approximately 554.60 sq mi. This statement is false.
New York has a larger land area than Delhi or Manila. New York's land area is approximately 4494.13 sq mi, Delhi's land area is approximately 750.86 sq mi, and Manila's land area is approximately 554.60 sq mi. This statement is true.
Final Answer The table supports the conclusion that the population of Manila is greater than the population of New York.
Examples
Understanding population density and land area is crucial in urban planning. For instance, city planners use these metrics to determine resource allocation, infrastructure development, and transportation needs. By comparing population densities, they can identify areas that require more schools, hospitals, or public transportation. This analysis ensures efficient urban development and improves the quality of life for residents. For example, if a city has a high population density but limited land area, planners might consider building upwards with high-rise buildings or investing in efficient public transportation systems.
The table supports the conclusion that the population of Manila is greater than that of New York since Manila's population is 21,241,000, while New York's is 20,673,000. Other conclusions do not hold in comparison of land areas. Therefore, the correct answer is option B.
