This statistic depicts the age distribution in Hong Kong from 2013 to 2023. In 2023, about 10.7 percent of the population in Hong Kong were 0 to 14 years old, 67.66 percent were aged 15 to 64, and 21.65 percent were 65 years of age or older.

Hong Kong’s population grew from around **** million in 1980 to around **** million at the end of 2024. Despite a slight decrease in population in 2020 and 2021, the population in Hong Kong has continued to increase. Population development in Hong Kong The population increase was not only due to natural population growth but also related to a significant inflow of immigrants from mainland China. As most immigrants were comparatively young, they also contributed to a higher birth rate. The total fertility rate in Hong Kong, however, which denotes the average number of children a woman has during her lifetime, already fell below the replacement level of around *** children per woman in 1980. Today, Hong Kong has one of the lowest fertility rates in the world. Nevertheless, the population of Hong Kong is still projected to continue growing due to immigration and reach *** million people in 2046. Age structure of Hong Kong’s population Hong Kong has a rapidly aging society. The median age of the population has more than doubled from **** years in 1970 to **** years in 2020, and it is expected to reach nearly ** years in 2060. Today, around two-thirds of the population is still in their working age, but the share of people aged 65 or older is increasing. Hong Kong has one of the highest life expectancies in the world, reaching around ** years for women in 2024.

In 2023, the elderly dependency ratio in Hong Kong increased to around ** percent, while the child dependency ratio decreased to around **** percent. The dependency ratio indicates how great a burden is placed on those of working age by those of non-working age. The source defines the working age between 15 and 64 years. The ratio is shown as the proportion of dependents per 100 working-age population.

ObjectiveTo elucidate the historical trends, underlying causes and future projections of esophageal cancer incidence in Hong Kong.MethodsUtilizing the Age-Period-Cohort (APC) model, we analyzed data from the Hong Kong Cancer Registry (1992–2021) and United Nations World Population Prospects 2022 Revision. Age-standardized incidence rates were computed, and APC models evaluated age, period, and cohort effects. Bayesian APC modeling, coupled with decomposition analysis, projected future trends and identified factors influencing incidence.ResultsBetween 1992 and 2021, both crude and age-standardized incidence rates of esophageal cancer witnessed significant declines. Net drifts exhibited pronounced downward trends for both sexes, with local drift diminishing across all age groups. Period and cohort rate ratios displayed a consistent monotonic decline for both sexes. Projections indicate a continued decline in esophageal cancer incidence. Population decomposition analysis revealed that epidemiological changes offset the increase in esophageal cancer cases due to population growth and aging.ConclusionThe declining trend of esophageal cancer in Hong Kong is influenced by a combination of age, period, and cohort. Sustaining and enhancing these positive trends requires continuous efforts in public health interventions.

From June to September 2022, around 99.9 percent of respondents in Hong Kong at an age between 25 to 34 had a smartphone. All age groups in Hong Kong revealed a growth trend in smartphone penetration since 2016.

From May to August 2023, around 99.8 percent of female respondents aged between 25 and 34 years old in Hong Kong had a smartphone. All age groups in Hong Kong revealed a growth trend in smartphone penetration since 2016.

According to a survey by Rakuten Insight on gym membership in Hong Kong in 2020, around ** percent of respondents aged between 16 and 24 said they held a gym membership, compared to ** percent of respondents aged between 25 years and 34 years. Physical Fitness & Yoga was the most popular gym among surveyed gym-goers.
