Question

free response questions: i a. define population density. b. explain how population distribution and density affect society or the environment. c. explain ways that geographers analyze population data. d. describe how population distribution affects the cultural landscape. e. identify a push factor that impacts migration. f. describe how the process of diffusion results in changes to the cultural landscape. g. explain a factor that accounts for contemporary population growth.

Explanation:

A. Population density is the number of people per unit of area (e.g., per square - kilometer or square - mile). It gives an idea of how crowded an area is.
B. High population density can lead to resource strain and environmental degradation, while population distribution affects infrastructure needs and social services. For example, densely populated urban areas need more housing, transportation, and sanitation.
C. Geographers use methods such as census data analysis, mapping (choropleth maps to show density, dot - density maps to show distribution), and demographic models to analyze population data.
D. Population distribution influences the cultural landscape by determining where different cultural groups live. Areas with diverse populations may have a mix of architectural styles, languages, and cultural practices.
E. A push factor for migration could be economic hardship (e.g., lack of job opportunities), political instability, or environmental disasters like droughts or floods.
F. Diffusion spreads cultural traits like ideas, technologies, and languages. This can change the cultural landscape, for example, the spread of fast - food chains globally has changed eating habits and the built environment with the construction of fast - food restaurants.
G. One factor for contemporary population growth is declining death rates due to improved healthcare and medical advancements, which allow more people to survive into adulthood and old age.

Answer:

A. Population density is the number of individuals per unit area.
B. High density can cause resource stress and environmental issues; distribution impacts infrastructure and services.
C. Use census data, mapping, and demographic models.
D. Determines where cultural groups live, influencing architecture, language, etc.
E. Economic hardship, political instability, or environmental disasters.
F. Spreads cultural traits, changing eating habits and built environment.
G. Declining death rates due to improved healthcare.
