There is no simple formula for population growth. Some of the factors that you need to take account of are: Emigration rates Immigration rates Demographics Age-specific fertility rates Death rates
Crude rates are rates calculated and applied for the entire population disregarding any categories such as gender or age. E.g. crude birth rate calculates the total number of births in a year over the total population including men, women and all children (provided they were not born that year).Specific rates are rates calculated considering categories or subgroups. E.g. birth rate calculates the total number of births in a year over the total number of women of child-bearing age.
They both have a 100% death rate (we all die sooner or later). However, until well into retirement ages, the death rate of male in a given age group will be higher than that for females. Early in life it is due to a larger rate of accidents and violent deaths, later due to higher rates of heart disease.

The crude death rate is the number of deaths in a population per 1,000 people, without considering age or other factors. Age-specific death rate, on the other hand, is the number of deaths within a specific age group per 1,000 people in that age group. Age-specific death rates provide a more detailed understanding of how mortality varies across different age groups within a population.

A demographer studies shifts in the characteristics of populations. They study birth rates, death rates, and the age of the population.
Health and health care. Age distribution (for death rate). Age distribution of mothers (for birth rate).
To construct a life table, you need data on births, deaths, and age-specific mortality rates in a given population. This data is used to calculate measures such as life expectancy, survival probabilities, and age-specific death rates. Life tables are commonly used in demography and actuarial science to study population dynamics and forecast future mortality patterns.
The science of demography focuses on the study of human populations, including their size, structure, distribution, and dynamics. It examines factors such as birth rates, death rates, migration patterns, and age distribution to understand population trends and how they impact societies.
There is no specific percentage of Americans who die of old age as the term "old age" is not typically used as a specific cause of death on death certificates. Instead, common causes of death in older adults include heart disease, cancer, and stroke.
Whereas age-standardization adjusts for underlying differences in the age distribution of the combined male-female population, age/sex-standardized rates adjust for differences in the population distribution by both age and sex simultaneously.Age/sex-standardized rates are NOT the same as sex-specific age-adjusted rates.Like age, sex has a powerful influence on disease rates. Males and females have markedly different incidence, prevalence, and mortality rates for certain diseases and males have a shorter life expectancy than females.Therefore, in order to fully account for these differences, researchers may want to adjust for both age and sex when making comparisons for some conditions.The calculation for age/sex adjustment differs from age-standardization in that the individual age-specific rates are stratified by sex and are applied to the standard population stratified by sex.The requirements for the calculation of age/sex standardized rates are:Study population by age and sexStandard population by age and sexNumber of events for males and females in the study populationFormulaei(f) is the number of events for females in age group iei(m) is the number of events for males in age group ipi(f) is the number of females in age group i the study populationpi(m) is the number of males in age group i the study populationPi(f) is the number of females in age group i in the Standard populationPi(m) is the number of males in age group i in the Standard populationFor each age stratum the expected number of events is the sum of the expected number of events for males plus the expected number of events for females in that stratumAge-specific expected events= Ei=[(ei(m) /pi(m) ) *Pi(m) ] + [ (ei(f) /pi(f) ) *Pi(f) ]The age/sex Standardized Rate (per 100 000) is the sum of all expected events divided by the total standard population= [ Sum(Ei)/Sum(Pi)] * 1000
No one is mentioned being that specific age at death.
There are many saints named Mary. Please be specific.
Expansive population pyramid: wide base and narrow top, indicating high birth and death rates. Constrictive population pyramid: narrow base and wider top, showing low birth and death rates. Stationary population pyramid: nearly equal widths at all age groups, suggesting stable birth and death rates.
The rates are as follows in the USA, note that there are no family rates: Age Over 16 $45 Age Under 16 $35
