{'density': [2, 0, 1, 3], 'total population': [1, 0, 0, 2], 'population': [3, 1, 2, 1], 'square kilometre': [2, 0, 0, 0], 'ratio': [1, 0, 1, 12], 'poverty line': [0, 1, 0, 2], 'kilometre': [1, 0, 0, 1]}
The density of population refers to the number of individuals living per unit area, usually measured as the number of persons per square kilometer. Option 1, which suggests the ratio of people living below the poverty line to the total population, is incorrect as it does not relate to population density. Option 3, which states the number of persons in a city, is too specific and does not encompass all areas. Option 4, which mentions the number of persons living per kilometer, is not precise enough as density is typically measured in terms of area. Therefore, option 2 is the correct answer as it accurately describes the concept of population density as the number of persons per square kilometer.
