Question 2.
List out the impacts on society if the sex ratio is too low or too high.
Answer:
Sex Ratio represents the number of females in per 1000 males in the population.
There are some regions that discriminate the genders and give priority to males over females. This results in a low sex ratio. The regions of low sex ratio are female infanticide and preferring a male child over the female. Low sex ratio indicates inequality between males and females and facilitates orthodox social norms like illiteracy among females, child marriages. This reduces childbirth.
High sex ratio implies equality between males and females. This means girls are more in number compared to boys, literacy among the females, no child marriages, no discrimination.
Question 3.
Compare Indian literacy rates with other countries:
Brazil, Sri Lanka, South Africa, Nepal, Bangladesh, Norway, Chile, Indonesia
What similarities and differences do you note?

A literate person is one who is above 7 years of age and can read and write any language with understanding.
Norway is a complete literate country. India ranks above Bangladesh and Nepal, whereas is below rest all other nations. India ranks 159 among 197 countries.
In India, one-third of the population cannot read and write. The probable reasons could be poverty, unemployment, population, regional hindrance etc.
Question 4.
Which areas of Telangana have a high density of population and what may be some of the reasons behind it?
Answer:
Telangana is a state in south India, that was formed in 2014 after separating from Andhra Pradesh. It is the 12th biggest state in the country. The regions with high population density are Hyderabad, Nizamabad, and Karimnagar. Due to infrastructure, public facilities and employment generation attracted more people to settle down here.
Question 5.
Distinguish between population growth and population change.
Answer:
When there is a high birth rate and low death rate, this leads to a sharp increase in population and therefore is population growth.
Population change is calculated by subtracting the current population to its previous years. This mainly occurs due to migration, births, deaths.
Population change (absolute number) = Population later date - Population at an earlier date
Population change in a place = (Number of births + number of in-migrants) - Number of deaths+ number of out-migrants)

• Which country’s population is likely to grow?

Mexico has the highest sex ratio.
