how is regular growth of population cause poverty?

Higher population implies a greater dependency burden. Moreover, for poor, greater number of members in the family implies greater earning hands. In addition to this, the bias in favour of the male child leads them to increase the family size irrespective of the consequences. Higher population implies lower per capita income. Also, it acts as a hurdle in the way of quality education, health care facilities and other facilities necessary for a quality life. Thus, high population leads to a low standard of living and aggravates poverty.
