List the attributes that populations but not individuals possess.

(N/A) population is defined as a group of individuals of the same species residing in a particular geographical area at a particular time and functioning as a unit.
The main attributes or characteristics of a population that individuals do not possess are:
$1$. Birth rate (Natality): It is the ratio of live births in an area to the population of an area. It is expressed as the number of individuals added to the population per capita.
$2$. Death rate (Mortality): It is the ratio of deaths in an area to the population of an area. It is expressed as the loss of individuals per capita.
$3$. Sex ratio: It is the ratio of the number of females to males in a population (e.g.,number of females per $1000$ males).
$4$. Age distribution: It is the percentage of individuals of different ages in a given population. The age distribution pattern is commonly represented through age pyramids.
$5$. Population density: It is defined as the number of individuals of a population present per unit area or volume at a given time.
