1. POPULATION DYNAMICS

2. Components of population dynamics Birth rate Death rate Total fertility rate Migration

3. The birth rate is the total number of lives per 1000 in a population in a year or period. The birth rate is usually given as the number of live births divided by the average population BIRTH RATE

4. 19 births per 1000 . 131.4 million births per year . 360000 births per day . 15000 births per hour. World 19.3 births per 1000 . 2.6 crore s births per year. 73 thousand births per year. 3 thousand births per hour. India Birth rate in india and world

5. D eterminants of high birth rate Early marriage lead to women starting to bear children at a younger age resulting in big families. Lack of public information on family planning .leads to ignorance of the benefits of a small family. Preference for sons is prevalent especially in developing countries where such tradition are still important .thus women have children until they give birth to sons thereby giving raise to large families . I lliteracy among people is also responsible for high birth rate as they don't know about preventive methods of pregnancy

6. Determinants of low birth rate Increase in education level( especially women).They become career minded therefore delay marriage and postpone marriage. The choice of more people to remain single. F ecundity : the physical ability of a woman to reproduce . Environment : unhealthy environment for having child or unfavorable conditions at the time of birth. More women go to school longer and enter the workforce : therefore delay marriage and have children later .

7. The ratio of death to the population of a particular periods of time ,usually calculated as the number of death per thousand people per year. The number of death per unit ,usually 1000 of population in a given place and time . Death rate

8. 8 death per thousand. 55.3 million death per year. 15 lakh death per day . 6,316 death per thousand. World 7.3 death per thousand. 97 lakh death per year. 26.5 thousand death per day. 1,116 death per hour India Death R ate in India and world

9. Determinants of high death rate I nsufficient nutrition. A high incidence of infectious disease. Drug addiction among pregnant women High birth rate among teenagers: since there body is not fully developed for having child so there is always a problem of low birth weights which is most important factor in infant death.

10. Determinant of lower D eath rate I ncrease food supplies and distribution . better nutrition to pregnant women and infant.
