Hint:
Across: 4- Emigration, 7- Birth, 8- Natality
Down: 1- Mortality, 2-Immigration, 3- Geometrical, 5-Density, 6-Malthus
The correct answer is: Across: 4- Emigration, 7- Birth, 8- Natality
Down: 1- Mortality, 2-Immigration, 3- Geometrical, 5-Density, 6-Malthus
- Emigration is moving out of current settlement while immigration is moving in to a new settlement.
- Natality is birth rate whereas mortality is death rate.
- All these factors are required to determine census.
