Population tends to be most dense along coast lines with flat plains, along rivers, in areas with fertile soil and temperate climates. Population density is lowest in areas where it is hard for humans to live. These include deserts, very rugged mountains, and arctic or subarctic regions where the climate is extremely cold.

What is demography cycle?
The demography cycle refers to the patterns of birth, death, and migration that occur in a population over time. These patterns can have significant impacts on the population's size, age distribution, and other demographic characteristics. Understanding these trends is important for policymakers and researchers to plan for future population changes.
What is the human pouplation?
As of 2021, the global human population is estimated to be around 7.9 billion. This number is constantly changing due to births, deaths, and migration patterns. The population is projected to continue growing in the coming decades.
Why does it appear that the human population does not follow the logistic growth curve?
The human population doesn't perfectly fit the logistic growth curve due to various factors, such as technological advancements that increase carrying capacity, migration patterns, and social dynamics influencing birth rates. Additionally, unpredictable events like wars, diseases, or natural disasters can disrupt population growth patterns. These complexities make it challenging for human population growth to conform strictly to a logistic model.
What is the study of the earth and patterns of human activities that place on its surface?
The study of the earth and patterns of human activities that take place on its surface is known as human geography. This field focuses on how people interact with the environment, including topics such as population, migration, urbanization, and cultural landscapes.
What are segregating sites in population genetics?
Segregating sites are positions in the genome where different individuals in a population have different nucleotides. These sites are important in studying genetic variation within a population and can be used to infer evolutionary relationships and patterns. The presence of segregating sites indicates genetic diversity within a population.
