241 (2) Over-population : In the chapter III, we have seen that there are evident signs of a tendency towards over- population. These are : (a) The birth-rate of the village is as high as 39,8 (b) The death-rate is also as high as 35.9 (c) The average expectation of life is as low as 27 years. (d) There is a continuous annual exodus of people from this village to outside areas for supplementing their meagre earnings from land. (e) The fact that the people of the village are not able to make both ends meet by their earnings in the village, but have to depend on external sources of income. This is evident from the following : (i) Deducting the income from external sources, for the village as a whole, from its total net receipts from all sources combined, we find that the average income per family comes to Rs. 306, while the average expenditure per family, as we have seen in the last section, is Rs, 334. (ii) Even taking the racial groups individually, a similar calculation shows that in the case of the Kaliparaj the average income per family comes to Rs. 260, the average expenditure being Rs. 284 ; and in the case of the Ujaliparaj the average income per family comes to Rs. 389 while the expenditure per family is Rs. 424, (3) Indebtedness : Reviewing the operation of these two causes together, we find that on the one hand there is low production and on the other, there is an excess of popula- tion so far as the means of subsistence available in the village are concerned. There is an intimate relation be- tween the two, each acting and reacting on the other. Over-population may be the cause of low production. It is equally true that low production may be the cause of over-population. At the present stage in the economy of this village both these forces are acting powerfully. We 31
