The objective of this analysis is to
Census of India systematically collects information about the population of India every 10 years. The last census report was published in the year 2011 and the next census is planned for the year 2021. The census data gives information about the prospective growth of the population of a country.
One of the primary duties of the Indian election commission of India is to verify the electors’ list, add new electors, remove electors in case of death and remove duplicates. The voting age of elections in India is 18 years and the electoral list consists of a population whose age is above 18 years.
The data source for this analysis is https://eci.gov.in/
If the electoral data is considered as data of a population whose age is above 18 years, then this analysis gives an indirect measure for the increase/decline/stagnated population in various states of India.
Also, this analysis resulted in an understanding of
Electors – Eligible to vote
Voters – Who voted in an election

Most of the states were formed, re-oriented in the period between 1950 to 1960. For consistency, below changes were made to the data
With the above changes, the below plot is made and it has
x-axis = Year of Parliamentary election y-axis = Electors OR Voters divided by 1,000,000 Line = Linear model regression line
- In most of the states, the gap between the electors' line & voters line are increasing OR same, which indicate "no improvement"/ "decrease" in Voting percentage. But this conclusion will be re-verified in the next plot. - Andhra Pradesh, Bihar, Gujarat, Karnataka, Madhya Pradesh, Maharashtra, Rajasthan, Tamil Nadu, Uttar Pradesh & West Bengal are considered as Big (OR) Highly populated states of India. - Assam, Chhattisgarh, Haryana, Jharkhand, Kerala, NCT of Delhi, Odisha & Punjab are considered as Medium size (OR) Medium populated states in India. - Andaman & Nicobar Highlands, Arunachal Pradesh, Chandigarh, Dadra & Nagar Haveli, Daman & Diu, Goa, Himachal Pradesh, Jammu & Kashmir, Lakshadweep, Manipur, Meghalaya, Mizoram, Nagaland, Pondicherry, Sikkim, Tripura & Uttarakhand are considered as Small size (OR) less populated states in India.
From the data, “Big OR Highly populated states” were filtered and the below plot was made. It has
x-axis = Year of Parliamentary election y-axis = Electors divided by 1,000,000 for various states
- Gujarat electors have grown almost 4.22 times from 1967 - Karnataka, Maharashtra & Rajasthan electors have grown almost 4 times from 1967 - West Bengal electors have grown almost 3.45 times from 1967 - Tamil Nadu has grown almost 2.81 times from 1967 - 18.99 million was the electors of Chattishgarh in 2019, which was separated from Madhya Pradesh.

Tamil Nadu is having the lowest electors growth in India compared to any other Big or Highly populated state.
The below plot is made after calculating the polling percentage from the given data.
Polling percent = Voters/Electors
The plot has
x-axis = Year of Parliamentary election y-axis = Polling % for various states
