$\Huge{Birth}$$\Huge{Rate}$

The birth rate (technically, births/population rate) is the total number of live births per 1,000 in a population in a year or period. The rate of births in a population is calculated in several ways: live births from a universal registration system for births, deaths, and marriages; population counts from a census, and estimation through specialized demographic techniques. The birth rate (along with mortality and migration rate) are used to calculate population growth.

Infant mortality rate (IMR) is the number of deaths per 1,000 live births of children under one year of age. The rate for a given region is the number of children dying under one year of age, divided by the number of live births during the year, multiplied by 1,000.

$\Huge{Enrolment}$$\Huge{Ratio}$

Gross Enrollment Ratio (GER) or Gross Enrollment Index (GEI) is a statistical measure used in the education sector, and formerly by the UN in its Education Index, to determine the number of students enrolled in school at several different grade levels (like elementary, middle school and high school), and use it to show the ratio of the number of students who live in that country to those who qualify for the particular grade level. The United Nations Educational, Scientific and Cultural Organization(UNESCO), describes ‘Gross Enrolment Ratio’ as the total enrolment within a country ‘in a specific level of education, regardless of age, expressed as a percentage of the population in the official age group corresponding to this level of education.’
