Dependency Ratio
A measure of the % of dependent people (not of working age) / number of people of working age (economically active).
![Page 4: Dependenct ratio, total fertality rate, prevelance](https://reader035.vdocument.in/reader035/viewer/2022062503/58f3813a1a28abad348b45e7/html5/thumbnails/4.jpg)
Definition
“In economics, geography and demography the dependency ratio is an age-population ratio of those typically not in the labor force (the dependent part) and those typically in the labor force (the productive part). It is used to measure the
pressure on productive population.”
The dependency ratio relates the number of children (0-14 years old) and older persons (65 years or over) to the working-age population (15-64 years old).

Importance & Data References
The dependency Ratio is important because it shows the ratio of economically inactive compared to economically active. Economically active will pay much more income tax, corporation tax, and, to a lesser extent, more sales and VAT taxes.
Past, current and projected dependency ratios are calculated for all countries by the Population Division of DESA and appear in the biennial United Nations publication, World Population Prospects.

Total Fertility Rate
The ratio of live births in an area to the population of that area; expressed per 1000 population per year.
![Page 10: Dependenct ratio, total fertality rate, prevelance](https://reader035.vdocument.in/reader035/viewer/2022062503/58f3813a1a28abad348b45e7/html5/thumbnails/10.jpg)
Fertility By Background Characteristics
Fertility analysis is of central importance in demographic analysis as births are a vital component of population growth.
Fertility level is directly affected by many socioeconomic factors; such as residence, education, and economic status, therefore, it is crucial to study the relationship between these factors and fertility.
![Page 11: Dependenct ratio, total fertality rate, prevelance](https://reader035.vdocument.in/reader035/viewer/2022062503/58f3813a1a28abad348b45e7/html5/thumbnails/11.jpg)
Definition
Total Fertility Rate (TFR), is the sum of the age-specific birth rates (5-year age groups between 10 and 49) for female residents of a specified geographic area (nation, state, county, etc.) during a specified time period (usually a calendar year) multiplied by 5.
(NOTE: This rate estimates the number of children a hypothetical cohort of 1,000 females in the specified population would bear if they all went through their childbearing years experiencing the same age-specific birth rates for a specified time period.)

PrevalenceA measure of disease that allows us to determine a person's likelihood of having a disease.
![Page 16: Dependenct ratio, total fertality rate, prevelance](https://reader035.vdocument.in/reader035/viewer/2022062503/58f3813a1a28abad348b45e7/html5/thumbnails/16.jpg)
Definition
Prevalence or prevalence proportion, in epidemiology, is the proportion of a population found to have a condition (typically a disease or a risk factor such as smoking or seat-belt use).
It is arrived at by comparing the number of people found to have the condition with the total number of people studied, and is usually expressed as a fraction, as a percentage or as the number of cases per 10,000 or 100,000 people.
Prevalence is contrasted with incidence, which is a measure of new cases arising in a population over a given period (month, year, etc.)

Example
With 4,000 people with the condition, Northern Ireland has one of the highest prevalence rates in the world. (BBC Apr 28, 2014)
the prevalence of obesity among American adults in 2001 was estimated by the U. S. Centers for Disease Control (CDC) at approximately 20.9%.
