Final answer:
Kerala has reduced its population through the reduction of family size, migration to urban areas, and the implementation of family planning policies and programs.
Step-by-step explanation:
Kerala, a state in India, has successfully reduced its population through various cultural factors. One significant factor is the reduction in family size. Traditionally, family size in India was large, resulting in a large population. However, in modern times, family size has been reduced to about three children, which has contributed to population control.
Another cultural factor that has influenced population reduction in Kerala is the migration of young people to urban areas in search of greater opportunities. This migration helps to decrease the population in rural areas and balances the population distribution.
Furthermore, Kerala has implemented policies and programs to encourage family planning and educate the population about the benefits of smaller families. These efforts have led to a decline in population growth and a more sustainable population size.
