Over 48 per cent of the Indian rural population is female. [66] 44.72 crore Indians are non-literate, more than a third of its 121.08 crore population. [67] Transgender people comprise 0.1% of India's rural population. The Andaman and Nicobar islands, West Bengal, Gujarat, Odisha and Mizoram have the highest proportions of transgender people.
The change in total population over a period is equal to the number of births, minus the number of deaths, plus or minus the net amount of migration in a population. The number of births can be projected as the number of females at each relevant age multiplied by the assumed fertility rate.
In ecology, a population is a group of organisms of the same species which inhabit the same geographical area and are capable of interbreeding. [2] [3] The area of a sexual population is the area where interbreeding is possible between any opposite-sex pair within the area and more probable than cross-breeding with individuals from other areas.
Between 1975 and 2010, the population doubled to 1.2 billion, reaching the billion mark in 2000.

In statistics, a population is a set of similar items or events which is of interest for some question or experiment. [1] [2] A statistical population can be a group of existing objects (e.g. the set of all stars within the Milky Way galaxy) or a hypothetical and potentially infinite group of objects conceived as a generalization from experience (e.g. the set of all possible hands in a game of ...
A population inversion (N 2 > N 1) has thus been achieved between level 1 and 2, and optical amplification at the frequency ν 21 can be obtained. Because at least half the population of atoms must be excited from the ground state to obtain a population inversion, the laser medium must be very strongly pumped.
Population density is an example of areal number density. The term number concentration (symbol: lowercase n , or C , to avoid confusion with amount of substance indicated by uppercase N ) is sometimes used in chemistry for the same quantity, particularly when comparing with other concentrations .
