Attributes of population are the characteristics that can be measured for an individual that are within a population. 

• Size: The total number of individuals
• Density: It is the number of individuals per unit area or volume. It tells how crowded or dense the population is.
• Age structure: Individual across different age groups
• Sex Ratio: it is the ratio of male to female in a population. 
• Birth rate: also known as natality. New individuals that are born in a population. 
• Death Rate: Rate at which the individual dies in a population. 
• Growth rate: Overall change in the population size over a specific time period. 
• Distribution: The arrangement of individual

Mortality: It is the death of individuals per 1000 people in 1 year 

Fertility rate: The average number of live birth per woman 

Life expectancy: The measure of the average time span an individual is expected to live. 

Sex Ratio: The ratio of males to females in a population is essential for understanding the reproductive dynamics and also the  breeding potential of the population.

The increase in population can be attributed by immigration and natality. 

The decrease in the population can be attributed to emigration and mortality
