Proportion of Population Aged 15-64　(coefficient of adult population or proportion of adult population) refers to the proportion of population aged 15-64 in the total population during the same period of time. It is an indicator of age structure, usually expressed in percentage.

Proportion of Urban　Population refers to the proportion of urban population in the total population during the same period of time. It is an indicator of population urbanization in a certain region, usually expressed in percentage.

Population Density　refers to the number of people located in a given land area at a certain point of time, usually expressed in the number of permanent population per square kilometer.

Sex Ratio　refers to the ratio of the male population to the female population among the total population (or population grouped by age), usually expressed in the number of males per 100 females. The following formula is used: Sex Ration=Number of Male Population / Number of Female Population ×100
