The human population is now about 7 billion. It reached 6 billion in _____.
- a. 2007
- b. 1999
- c. 1802
- d. 1350
Concept introduction: Population is the total number of organisms present in a specified area and they are capable of interbreeding. Demography is a study of characteristics of the human population about its size, density, and distribution. It is a statistical interrelationship between the population and economic development.
Reasons for correct statements:
Demographic studies reveal the statistical composition of a particular human population. The human population is estimated as 7.62 billion as of May 2018.
Option b. is given as, “1999.” Demographic studies estimated that the global population of human was 6 billion. Hence the correct answer is option b.
Reasons for incorrect statements:
Option a. is given as, “2007”...
