Science in Personal and Social Perspectives (9 - 12)Characteristics and changes in populations
Human populations include groups of individuals living in a particular location. One important characteristic of a human population is the population density--the number of individuals of a particular population that lives in a given amount of space.
The size of a human population can increase or decrease. Populations will increase unless other factors such as disease or famine decrease the population.
