Determine the percentage of the population that is literate within a specific age group.

The Literacy Rate is: 0%

How to Calculate Literacy Rate

The literacy rate is a critical indicator used to measure the educational level and human development of a specific region, country, or demographic. It represents the percentage of people aged 15 and older who can both read and write with understanding a short simple statement about their everyday life.

The Literacy Rate Formula

Literacy Rate = (Number of Literate Persons / Total Population) × 100

Step-by-Step Calculation Guide

  1. Define the Population: Identify the specific age group you are measuring (traditionally those 15 years and older).
  2. Count Literate Individuals: Determine the total number of people within that group who possess basic reading and writing skills.
  3. Identify Total Population: Find the total number of people within the same age group, regardless of their literacy status.
  4. Divide: Divide the number of literate persons by the total population.
  5. Convert to Percentage: Multiply the result by 100 to find the final literacy rate percentage.

Practical Example

Imagine a small town where the population aged 15 and older is 5,000. Through a recent census, it was discovered that 4,250 of these residents can read and write effectively.

  • Step 1: Literate Population = 4,250
  • Step 2: Total Population = 5,000
  • Step 3: 4,250 ÷ 5,000 = 0.85
  • Step 4: 0.85 × 100 = 85%

In this example, the town has a literacy rate of 85%.

Why is this Metric Important?

Governments and NGOs use literacy rates to monitor the effectiveness of education systems and to identify areas that require additional funding or educational resources. A high literacy rate is strongly correlated with better health outcomes, economic growth, and social stability.
