In India census is taken in a decade time gap and analysed. It is stated that to determine whether a country is developed, developing or under developed a record of population density is key. Along with population density important factors affecting are birth rate and death rate. It’s important to understand the every social issue with sociological perspectives. Over population is the main social problem of India. Number of infants born in a given year within a country, state or city is known as birth rate of that place. Similarly, no. of deaths recorded within a year about a place is known as death rate of that place. The advancement in technology is clearly seen in this situation. For example, country like Kenya has high birth rates and death rates although the country will have a decent population in one sight but it clearly marks the failure of technological development in field of sciences, medicine and thereby we come across the term average life expectancy. For Kenya it is in range of 40s. Discussing about developed countries like USA has very low birth rate and death rate showing their awareness levels and technological enhancement.
