The aging index refers to the number of the elderly aged 65 years and over per 100 individuals younger than 14 years old in a specific population. Thus, the higher the index is, the older the population results. According to estimates for 2025, there are slightly more than two elderly people for every young individual in Italy. Between 2010 and 2025, this figure increased steadily.

Survey for the calculation of the Active Ageing Index of the City of Madrid. OBJECTIVE OF THE STUDY: Know the result of certain indicators that allow to calculate the Active Ageing Index. The Active Ageing Index is an ideal tool both for comparison with other areas or cities and for its value in long-term longitudinal monitoring. Compare the potential of older people to have active and healthy aging. The index measures the independent standard of living of older people, their participation in paid work and social activities, as well as their ability to age actively. It is carried out for citizens over 55 years of age residing in the municipality of Madrid. It is part of the evaluation of the Madrid Plan Friendly with the Elderly, as an impact indicator. It consists of 22 indicators that are grouped into four dimensions: employment, social participation, independent and safe living, and capacity for healthy ageing.
According to estimates for 2025, there will be 199.9 older adults for every 100 young people in South Korea. This ratio is expected to more than triple by 2072.

Several indicators are calculated: — the share of 65 years of age and over in the total population of the entity — the dependency index: This is the ratio between the population under the age of 20 or 65 years and older (numerator) and the population aged 20-64 (denominator). An index of dependence in below 100 indicates a larger share of the working-age population. — the ageing index: The Ageing Index is the ratio between the population aged 65 and over (numerator) and the population under 20 years of age (denominator). An index above 100 indicates that the share of people over 64 in the population is higher than that of those under 20. — the index of ageing intensity: The Aging Intensity Index is the ratio between the population aged 80 and over (digital) and the population aged 65 and over (denominator). It makes it possible to measure the share of older people (with a greater risk of loss of autonomy) among those aged 65 and over.

Introduction: The Healthy Ageing Index (HAI) has been shown not only to have wider applicability and predictive ability but also to adequately predict mortality in Western populations. There is still a lack of studies validating the applicability of the HAI in China. Objective: To evaluate the applicability of the HAI and validate whether the HAI is suitable for monitoring ageing in the elderly population in China. Methods: Data were obtained from the Rugao Longevity and Ageing Study. The modified HAI was constructed based on systolic blood pressure, chronic pulmonary diseases, cognitive function, fasting glucose, and kidney function. It was calculated in 1719 individuals aged 70–84 years at baseline. The adverse outcomes were mortality and disability. Demographic, physiologic, and clinical data were collected. Cox proportional hazards and logistic regression models were used to analyze the relationship between the modified HAI and adverse outcomes. Results: A total of 1,719 older adults were analyzed in our study. A total of 793 (46.13%) males were recruited. The mean age was 75.69 ± 3.93 years. At the 5-year follow-up, there were 266 deaths and 275 individuals with disabilities. In the multivariable models, the modified HAI was associated with mortality (hazard ratio = 1.11, 95% confidence interval [CI]: 1.03–1.20) and disability (odds ratio = 1.11, 95% CI: 1.05–1.18). In the sensitivity analyses, similar associations remained after imputing missing data using multiple imputation and excluding participants with major cardiovascular disease at baseline. Conclusion: The modified HAI was a robust and independent predictor of adverse outcomes. It is a valid and feasible tool for monitoring ageing in older adults.

Taiwan Aging Index data was reported at 68.200 % in 2010. This records an increase from the previous number of 40.400 % for 2000. Taiwan Aging Index data is updated yearly, averaging 10.600 % from Dec 1956 (Median) to 2010, with 8 observations. The data reached an all-time high of 68.200 % in 2010 and a record low of 5.600 % in 1956. Taiwan Aging Index data remains active status in CEIC and is reported by Directorate-General of Budget, Accounting and Statistics, Executive Yuan. The data is categorized under Global Database’s Taiwan – Table TW.G002: Population: Population and Housing Census.
Throughout the depicted time frame in Argentina, the aging index has undergone a general rise, starting from 34 in 1970 and progressing to 53 in 2022.

An index of dependency in below 100 indicates a larger share of the working-age population. - the ageing index: The ageing index is the ratio between the population aged 65 and over (numerator) and the population aged under 20 (denominator). An index above 100 indicates that the share of those over 64 in the population is higher than that of those under 20. - the intensity index of ageing: The age intensity index is the ratio of the population aged 80 and over (numerator) to the population aged 65 and over (denominator). It measures the share of older people (at greater risk of loss of autonomy) among those aged 65 and over.

This Alberta Official Statistic describes Sex Ratio, Total Dependency Ratio, and Aging Index for Alberta and Canada for two census periods, 2006 and 2011. The sex ratio is the ratio of males to females in a given population, usually expressed as the number of males for every 100 females. The sex ratio at birth in most countries is about 105 or 106 males per 100 females. After birth, sex ratios vary because of different patterns of mortality and migration for males and females within the population. Dependency ratio (age dependency ratio) is the ratio of persons in the "dependent" ages (generally under age 15 and over age 64) to those in the "economically productive" ages (15 - 64 years) in a population. The age-dependency ratio is sometimes divided into old-age dependency (the ratio of people ages 65 and older to those ages 15-64) and child-dependency (the ratio of people under age 15 to those ages 15-64) ratios. The sum of these two is the Total (age) dependency ratio. This ratio is often used as an indicator of the economic burden the productive portion of a population must carry - even though some persons defined as "dependent" are producers and some persons in the "productive" ages are economically dependent. Countries with very high birth rates usually have higher dependency ratios because of the large proportion of children in the population. The Aging Index is the ratio of persons aged 65 years and over to every 100 persons under age 15 years. It is a measure of aging of a population. The aging index shows that Alberta’s population is younger than that of Canada.
Projected aging index of Ulsan surged by 9.01% from 44.4 number of people 60 years and older per 100 youth 0-14 years in 2012 to 48.4 number of people 60 years and older per 100 youth 0-14 years in 2013. Since the 8.20% surge in 2003, projected aging index soared by 144.44% in 2013.
The aging index refers to the number of the elderly aged 65 years and over per 100 individuals younger than 14 years old in a specific population. Thus, the higher the index is, the older the population results. According to estimates for 2025, there are slightly more than two elderly people for every young individual in Italy. Between 2010 and 2025, this figure increased steadily.
