= Literacy Rate =

Definition
Total number of literate persons in a given age group expressed as a percentage of the total population in that age group. The adult literacy rate measures literacy among persons aged 15 years and above, and the youth literacy rate measures literacy among persons aged 15 to 24 years.

List of Literacy rate for all countries is calculated and published by different institutions like UNESCO,World Bank etc. worldwide on regular basis.

General Calculation Method
Divide the number of literates of a given age range by the corresponding age group population and multiply the result by 100. Alternatively, apply the same method using the number of illiterates to derive the illiteracy rate; or by subtracting the literacy rate from 100%.

Data Required
Population and number of literates (or illiterates) by age range.

Data Source
Mainly national population census; household and/or labour force surveys.

Interpretation
A high literacy rate (or low illiteracy rate) suggests the existence of an effective primary education system and/or literacy programmes that have enabled a large proportion of the population to acquire the ability of using the written word (and making simple arithmetic calculations) in daily life and to continue learning. It is common practice to present and analyse literacy rates together with the absolute number of illiterates as improvements in literacy rates may sometimes be accompanied by increases in the illiterate population due to a changing demographic structure.
