Population and Geographical Area
It is of interest to look into which are the most densely populated villages. We can do this by creating a simple scatter plot between population of village and the total geographical area of a village.
Irrigation for Agriculture
The census provides the net area sown (hectares) in a village along with area irrigated with water source in hectares. The area under irrigation may be affected by several factors.
Area Sown vs Area under Irrigation
A distribution for the percentage of area irrigated will be interesting to look at.
Understanding what drives area under irrigation
Much is heard about rain fed agriculture in India. There are several factors that can affect area under irrigation - ranging from government supports, demographics, distance from urban clusters and several known and unknown variables. With the given data we can check if the following variables have any relation with area under irrigation:
- Percentage of Marginalised group population in village
- Distance from Major government offices
- Distance from urban center
- Total population of a village
A simple Linear regression to see if the above explanation has any merit
