Age distribution of population refers to the percentage of people in different age groups within a given population. This information provides insights into the demographic structure of a society, such as the proportion of children, working-age adults, and elderly individuals. It is used to understand trends in population growth, age-related policies, and potential social and economic impacts.
A ratio of individuals with a particular phenotype to the total number of individuals in the population. Individuals with certain phenotype --------------------------------------------------- (Over) Total # of individuals within the population The distribution of traits in a population

The proportion of the population that holds one opinion compared to those with opposing opinions or no opinion is referred to as the opinion ratio or distribution. It provides insight into how prevalent a particular view is within the population and can help understand the diversity of opinions on a given issue. Analyzing this ratio can be useful for decision-making and forming strategies that consider various viewpoints.
The distribution of the population according to the different types of occupations is referred to as the occupational structure. Occupations are generally classified as primary (agriculture, mining, fishing, etc.), secondary (manufacturing industry, building and construction work, etc.) and tertiary (transport, communications, banking, etc.). The proportion of people working in different activities reflects the economic development of a country. Developed nations have a high proportion of people in secondary and tertiary activities. Developing countries tend to have a higher proportion of their workforce engaged in primary activities.

Imbalance is the state or condition of lacking balance, as in proportion or distribution.
Some different characteristics of populations include size (total number of individuals), density (number of individuals per unit area), distribution (spatial arrangement of individuals), age structure (distribution of individuals by age), sex ratio (proportion of males to females), and growth rate (change in population size over time).
