# Population

- Age-Specific Death Rate - The age-specific death rate is a measure used to quantify mortality risk for specific age groups within a population. This calculator helps calculate the rate.
- Batesian Mimicry Ratio - The Batesian mimicry ratio measures the proportion of mimic species to harmful species within an ecosystem.
- Dependency Ratio - The dependency ratio is a demographic measure that shows the pressure on the working population to support non-working age groups.
- IPAT Equation for Environmental Impact - The IPAT equation (Impact = Population × Affluence × Technology) is used to measure human impact on the environment, taking into account population size, level of affluence, and technology impact.
- Net Migration Rate - The net migration rate calculator provides the net migration rate per 1,000 people based on immigration, emigration, and total population.
- Old-Age Dependency Ratio - The old-age dependency ratio is calculated as a percentage of the elderly population to the working-age population. Use this calculator to determine the ratio and understand its implications.
- Population Momentum - Population momentum calculator estimates continued population growth even with declining fertility using net reproduction rate.
- Population Pyramid Analysis - Population Pyramid Analysis is a method of visualizing the age and sex structure of a population.
- Replacement Fertility Rate - The replacement fertility rate is the average number of children that must be born to a woman in order to replace the population itself, taking into account mortality and other factors. This calculator helps find the replacement fertility rate.
- Standard Deviation (Population) - Standard deviation is a statistical measure of the spread or variability of a dataset. Calculate the population standard deviation using the provided formula.
- Urbanization Rate - The urbanization rate is the percentage of the total population that lives in urban areas. This calculator helps find the urbanization rate.
