1.	What are the forms of total population? Write in brief.
Answer» Following are the forms of total Population: (a) Birth rate & Death rate: It is the no of individual increases or decreases to the total no of individual in a population respectively. (b) Sex ratio: It is the total no of females per thousands of male in the population. (c) Age pyramids: For human population the age pyramids generally shows age distribution of male and female in a combined diagram. The shape of the pyramid reflects the growth status of the population. (d) Population Density: It is the no. of individual per unit area. If N is the population density at time 't' then density at time t + 1 is N_t+1 = N_t + [(B+I) - (D+E)] Where B → Natality I → Immigretion E → Emigration D → Mortality

Answer»

Following are the forms of total Population:

(a) Birth rate & Death rate: It is the no of individual increases or decreases to the total no of individual in a population respectively.

(b) Sex ratio: It is the total no of females per thousands of male in the population.

(c) Age pyramids: For human population the age pyramids generally shows age distribution of male and female in a combined diagram. The shape of the pyramid reflects the growth status of the population.

(d) Population Density: It is the no. of individual per unit area. If N is the population density at time 't' then density at time t + 1 is

N_t+1 = N_t + [(B+I) - (D+E)]

Where

B → Natality

I → Immigretion

E → Emigration

D → Mortality
