Answer 1

Q1.

a) Number of children born per female was 3.8 in 1900,3 in 1940, 4 in 1950, 2 in 1990-2000

b)This shows number of children born per female decreased to 3 in 1940 then increases till 1950 and decreased to 2 in 2000

c) In 1900, 50% of household have 6 or more people; in 1950, 20% of household have 6 or more people; in 1998 10% household have 6 or more people.

Q2.

From both graphs we can observe that as number of children born per female is directly proportional to number of persons in household that means as number of children born per female decreases number of persons in household also decreases.Alternatively as number of persons in household decreases number of children born per female also decreases in this way both grahs relate to each other.

Q.3

As advancement in engineering and environmental awareness increases the number of children born per female and number of persons in household decreases.
