1. Write the importance of Census.
→The census tells us who we are and where we are going as a nation, and helps our communities determine where to build everything from schools to supermarkets, and from homes to hospitals. It helps the government decide how to distribute funds and assistance to states and localities.
2. Why does the population increase at a fast rate
→This rapid growth increase was mainly caused by a decreasing death rate (more rapidly than birth rate), and particularly an increase in average human age. By 2000 the population counted 6 billion heads, however, population growth (doubling time) started to decline after 1965 because of decreasing birth rates.
3. What do you understand by birth rate and deat
→Birth Rate (or crude birth rate) The number of live births per 1,000 population in a given year. Not to be confused with the growth rate. Death Rate (or crude death rate) The number of deaths per 1,000 population in a given year.
