Quantitative data
Numerical information or data that can be measured or expressed in terms of quantity, such as statistics, measurements, or counts.
Qualitative data
Descriptive information or data that is not numerical but instead provides insights, opinions, or interpretations based on qualities, characteristics, or attributes.
Rank-Size Rule
A principle observed in urban geography where the population size of cities within a country or region is inversely proportional to their rank in a hierarchical order, with the largest city being approximately twice the size of the second-largest city, three times the size of the third-largest city, and so on.
Redlining
A discriminatory practice in housing and lending whereby financial institutions or government agencies refuse or limit loans, mortgages, or insurance to certain neighborhoods or communities, typically based on their racial or socioeconomic composition.
