Differentiate natality rate and mortality rate.

In a population of an area, the difference in the natality rate and mortality rate is zero in a particular year, but the population density has decreased. Which of the following may be the reason for this decrease ?

Differentiate y=tanx

What is mortality rate?

(a) Write any two differences between Natality and Mortality rates. (b) Explain three kinds of population with regard to age distribution.

If natality rate is parallel to mortality rate then population is :

Assertion : Population of India crossed 1 billion in May 2000. Reason : It is the result of rapid decline in death rate, maternal mortality rate (MMR), and infant mortality rate (IMR) as well as an increase in the number of people in reproducible age.

Which of the following can be taken as characteristic demographic features of the development countries? (a) High fertility rate (b) Rapidly rising mortality rate. (c ) Very young age distribution. (d) Rapid population growth ( e) Rapidly falling mortality rate (f) Very old age distribution.
