It's called the Dependency Ratio
The Shiites are around 15% of total Muslim population while Sunnis are around 85%. So, the ratio of Sunnis to Shiites is around 6 to 1
The ratio of the population ages 15 or over is 1.06 males per female.
The male to female ratio globally is approximately 1:1. There are slight variations between countries and regions due to factors such as life expectancy and population distribution.
The average on-duty police-to-city population ratio varies significantly depending on the size and needs of the community. In general, a common benchmark is around 2-3 police officers per 1,000 residents in a given city. However, this ratio can be higher or lower based on factors such as crime rates, community demographics, and budget constraints.
In humans the secondary sex ratio is commonly assumed to be 105 boys to 100 girls (which sometimes is shortened to "a ratio of 105"). In human societies, however, sex ratios at birth or among infants may be considerably skewed by sex-selective abortion and infanticide. The CIA estimates that the current world wide sex ratio at birth is 107 boys to 100 girls.
"The dependency ratio is used in Economics to measure the working population and non working population. It is age-population ration, and takes into account both dependents and productive populations."
Dependency ratio is essentially the number of working individuals in a population compared to the non-working. A declining working population is supporting an ever larger number of retired persons.
Old age dependency ratio is a demographic indicator that measures the number of elderly people (usually age 65 and older) in a population compared to the working-age population (usually age 15-64). It is used to assess the potential economic burden placed on the working-age population to support the elderly. A higher old-age dependency ratio indicates a larger proportion of elderly individuals relative to the working-age population.
Sex ratio is ratio of males to females in a population.
The ratio of (distance) / (time), called "speed".The ratio of (speed) / (time), called "acceleration".The ratio of (force) / (area), called "pressure".The ratio of (force) / (acceleration), called "mass".The ratio of (mass) / (volume), called "density".The ratio of (distance) / (volume), sometimes called "fuel economy".The ratio of ( 1 ) / (time), called "frequency".The ratio of (energy) / (time), called "power".
In demography, a dependency ratio is usually the ratio of the non-productive members of the population to the productive members. This is because the econmic well-being of the whole population - the productive and non-productive members - depends on the value produced by the productive part. The non-productive population comprises the youngsters (aged up to 15), and the older people (aged 65 and over) while the productive part is the population aged 15 to 64. The ratio is usually expressed as a percentage. A high ratio means that each working person is, effectively supporting, more people.
It is the ratio between the size of the sample and the size of the population.
In the United States, the ratio of firemen to population is: 2.5 firefighters per 1000 of population. This has been a constant ratio for the last couple of years.
