We (Sumona and George) were interested in smaller families versus longer lives. We particularly choose two most populated countries in the world China and India. In 1800 China’s life expectancy was 32 years compared to India’s as 25 years whereas the # of children per women 5.5 for China and 5.93 for India. It has changed over the years significantly. In 2010 China’s life expectancy has gone upto 75 years and India’s 65years and the number of children per woman 1.42 for China and 2.63 for India.
