It's called the Dependency Ratio
The ratio of non-working population to working age population is called the dependency ratio. It is used to assess the pressure placed on the working population to support the dependent population.
The global Muslim population is approximately 85-90% Sunni and 10-15% Shia. The exact ratio may vary by region.
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.
Previous answer of: "the ratio is 1:3" is very incorrect. It suggests that for every one person in China there are three people in Australia. On the 1st of November 2010 (the last census), China was 1,339,724,852 On the 5th of February 2012, Australia's estimated population was 22,823,153 This gives a China:Australia ration of 58.7:1 - so for every 58.7 people in China there is one person in Australia. The reverse ratio, Australia:China, would be 1:0.017 - so for every one person in Australia there is 0.017 of a person in China.
"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."
The youth dependency ratio is a demographic indicator that compares the number of children and young people in a population to the working-age population. It is calculated by dividing the number of people aged 0-14 or 0-19 by the number of people aged 15-64, then multiplying by 100. A higher ratio indicates a larger proportion of dependents relative to the working-age population.
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.
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.
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".
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.
