πŸ‘₯ Introduction

Population composition refers to the structure of the population in terms of age, sex, literacy, occupation, language, religion, and ethnicity. It helps us understand the social and economic characteristics of a population.

πŸ“Š Age Structure

The age structure refers to the distribution of the population in different age groups. It is usually divided into:

🚹🚺 Sex Ratio

Sex ratio is the number of females per 1000 males in the population. It indicates gender balance and social status of women in a society.

For comparisons, always record the country, year, age group and definition used by a dataset. Sex ratio conventions differ between sources, so avoid comparing figures without checking the denominator.

πŸ“š Literacy Rate

Literacy is the ability to read and write. The literacy rate is the percentage of literate people aged 7 years and above in the population.

Literacy statistics depend on the source, reference year and age threshold. In a data response, state these details rather than presenting an undated percentage.

πŸ‘¨β€πŸ”§ Occupation

Population can be classified based on their occupations into:

🌍 Language and Religion

People around the world are diverse in terms of language and religion. These characteristics influence culture and lifestyle.

πŸ“– Conclusion

The composition of population helps in understanding the quality of human resources and planning for development, education, healthcare, and employment opportunities.
