To What Extent Did Indian States with Lower Literacy Rates in 2001 Experience Greater Improvements in Literacy by 2011?

Literacy is a crucial indicator of social and economic development. Greater literacy rates can lead to improvements in employment opportunities, better health, a higher standard of living and increased participation of the community. There have been substantial differences between literacy levels and educational access across different states and union territories. According to census data, the national literacy rate increased from 64.8% in 2001 to 73% in 2011, showing the immense progress taken over the decade.

However, the growth of literacy rates has not been similar in all states and union territories. Some areas have had dramatic improvements whereas some have had only mild changes. This creates a question whether states that started with low literacy rates were able to increase their literacy levels at a faster rate than sates and union territories at initially greater literacy levels.

Methodology

The dataset contained literacy statistics for Indian states and union territories from 2001 and 2011. The first step of the process was cleaning the data using python in google collab. All data was checked for missing values, repeated information, wrong data types and inconsistent labels. Another dataset was obtained from secondary sources relating differences between urban and rural literacy rates. After which tableau was used to create graphs and visualizations that helped me understand trends and relationships within the data.

Figure 1: Initial literacy vs literacy growth in Indian states

Figure 1 is the most crucial graph in this investigation because it helps directly find out the connection between literacy levels in 2001 and literacy growth in the following years. The scatter plot diagram shows a clear negative sloping trend, clearly indicating that states with lower literacy rates initially had greater increase in the following years. Analysis shows that the mathematical coefficient of this relationship is -0.70 between literacy rates and literacy growth.

An example of this is Bihar. They had an initial literacy rate of 47% in 2001 but they had a literacy increase of 14.8 percentage points in 2011. Similarly, Jharkhand, Arunachal Pradesh, Jammu and Kashmir and Uttar Pradesh all had similar situations.

On the other hand, states with high literacy rates such as Kerala experienced smaller changes within the same period. This could be due to states with high literacy rates being unable to find scope for greater improvement whereas lower other states find it easy to improve by increasing the number of schools or educational opportunities being provided.

Figure 2: literacy growth by state and union territory

Figure 2 puts different states and union territories based on literacy growth during the decade.

Dadra and Nagar Haveli had the largest improvement which recorded literacy growth of 18.6 percentage points. Bihar ranks second with a growth of 14.8 percentage points with Tripura, Nagaland, Jharkhand, and Sikkim also having great gains.

Mizoram ranks lowest on the list with a growth of only 2.5 percentage points, while Kerala ranked second last with an increase of only 3.1 percentage points. Chandigarh, Delhi and Puducherry also had extremely small changes.

This data further supports the pattern identified in figure 1. States with lower literacy rates in 2001 had greater improvements while other highly literate state had less room for growth. Once literacy rates go higher further progress is difficult. The differences in growth show the differences in the quantity and quality of educational systems available throughout India.

Figure 3: Average Rural Vs Urban Literacy Growth

Figure 3 compares literacy rates between rural and urban areas.

Results show rural literacy grew by 8.73 percentage points on average while urban literacy by only 4.12 points.

Since rural communities had lower rates of literacy, they had greater chances of improvement. Government education initiatives, schooling and increased awareness of opportunities. Urban areas already had higher literacy rates at the start. As a result, growth rates were smaller because literacy levels were closer to the theoretical maximum. The comparison between these two factors provides greater reinforcements to the broader conclusion that areas with lower initial literacy rates experience faster progress.

Figure 4: Top 10 Literacy States

In 2011 after all progress Kerala ranked first with a literacy rate of 94.0%, followed by Lakshadweep at 91.8% and Mizoram at 91.3%. Goa, Tripura, Daman and Diu, the Andaman and Nicobar Islands, Delhi, Chandigarh, and Puducherry also achieved literacy rates above 85%.

Overall India has done a great job in increasing their total literacy rates and bridging the gap between rural and urban areas and different states and union territories.
