3. The sex ratio (Males: Females) in the world is 1.07 at birth, 1.06 for under age 15 years, 1.02 for 15-64 years, and 0.78 for 65 years and over.
Explain this statement. [2]
Birth time ratio 1.07
ubder 15 ratio 1.06
15 to 64 ration 1.02
and above 64 ratio 0.76
ratio 1.07 means
if male 1007 female 1000
Male e populations maximum as compared to female. But if your age increases then we can see ratio is decreases
ratio 1.02
male 1002 female 1000
4 people differance between birth time ratio and this ratio
now above 64 ratio is 0.78
it means male 780 female 1000
very big difference.it clearly means that male death rate is maximum.. 20% males death before age of 64, but females are long liveing...

Amajor actor in the wide range of growth rates in various parts of the world is the differences in their age structures. The age Mructures of populations are often depicted as population pyramids post-reproductive years reproductive years pre-reproductive years male female Age 85+ 80-84 75-79 70-74 65-69 60-64 55-59 50-54 45-49 40-44 35-39 30-34 25-29 20-24 15-19 10-14 5-9 0-4 A B.

6. A study exploring the lives of Canadian males in various states of health presents an interesting application of the life table [14]. When constructing their table, the authors divided the person-years lived during a given age interval, n^x, into person- years lived inside institutions and person-years lived outside institutions. The life table can now be used to determine the average remaining years of life outside nstitutions Number Rate of Person-Years of Life Lived Person-Years in Institutions Alive Institutionalization 100,000...
