(Central News Agency reporter Ho Hsiu-ling, Taipei, April 17) Yongqing Housing stated that due to declining birth rates, later marriages, and an increase in single individuals, household composition is trending towards smaller sizes. According to statistics from the Ministry of the Interior, the average population per registered household in Taiwan has decreased from 3.20 people in Q4 2021 to 2.89 people in Q4 2025. Observing the six major cities plus Hsinchu County/City over the past five years, the proportion of small apartment transactions (under 25 ping) has continued to rise.
Yongqing Housing announced today via press release that over the past five years, the average population per registered household in the six major cities plus Hsinchu County/City has shown a downward trend, all falling below the 3-person mark. Among them, Taichung City saw the largest decrease of 0.40 people, followed by Tainan City with a decrease of 0.32 people.
Chen Chin-ping, Deputy Manager of Yongqing Housing Research and Development Center, pointed out that the decrease in household population reflects phenomena such as declining birth rates and later marriages, with family structures shifting from multi-person households to small families, or even single-person living. In addition to the decrease in household population, against the backdrop of continuously rising housing prices, small apartment products with more affordable total prices are gradually gaining market favor.
According to statistics from Yongqing Real Estate Group, the proportion of small apartment transactions in the six major cities plus Hsinchu County/City has significantly increased over the past five years. Comparing 2025 to 2021, Kaohsiung City saw the largest increase of 7.5 percentage points, followed by New Taipei City with 6.7 percentage points.
Chen Chin-ping explained that in recent years, with the establishment of science parks and the advancement of transportation infrastructure, Kaohsiung has experienced continuous population inflow. Coupled with rising land and construction costs, prices for large apartments have increased, leading homebuyers to turn to lower-priced small apartments. Developers, in response to market demand, have launched small apartment products in city centers and along MRT lines, boosting transaction proportions.
In New Taipei, due to the planning of a large number of small apartments in redevelopment zones such as Banqiao, Sanchong, Tamsui, and Xinzhuang, and prices being relatively more affordable than Taipei City, small apartments with convenient transportation and living functions have become the preferred choice for first-time homebuyers and single individuals.
Furthermore, observing changes in average total prices, small apartments in the six major cities plus Hsinchu County/City have seen a comprehensive increase in average total prices over the past five years. Comparing 2025 to 2021, Hsinchu County/City climbed from NT$3.29 million to NT$5.22 million, a surge of 58.7%; Taoyuan City also saw an increase of 34.5%, New Taipei City 27.4%, and Taipei City 17.9%. With the increased demand for small apartments, prices have steadily risen.
Regarding Hsinchu County/City, which had the highest increase, Chen Chin-ping pointed out that even though Hsinchu's tech professionals have higher salaries, the pressure to buy a home remains significant, leading some buyers to choose small apartments with lower total prices. Additionally, the increase in student and working populations in the area has driven rental demand, increasing the acceptance of the small apartment market. (Editor: Pan Yi-ching) 1150417
