台灣近30年住宅數據顯示,每戶平均居住坪數由1995年的37.2坪升至2018年峰值45.2坪後回落至2025年的40.2坪,但每人平均居住坪數則從9.43坪升至14.93坪,增長58.3%,主因是少子化與家庭結構核心化導致分母縮減快於分子。自有住宅率維持高於83%,租屋比例反而下降,顯示台灣人寧願背負房貸也願擁有小宅,而非長期租屋。

〔記者高嘉和/台北報導〕30年的住宅數據,宛如一部台灣社會變遷的縮影。根據主計總處最新「家庭住宅狀況」調查,從1995年至2025年的近30年光陰,台灣每戶居住坪數「由小變大,又從大縮小」,但同期間每人平均居住坪數卻逆勢成長。數據背後折射出台灣房價狂飆與人口結構轉變的無奈現實。
1995年,當時每戶平均居住坪數約37.2坪;隨著財富累積與居住品質提升,到了2018年達到歷史高點的45.2坪。但到了2025年,每戶平均居住坪數明顯縮水至40.2坪,短短7年間縮水5坪,反映出都會區寸土寸金、房價所得比屢創新高的現實,建商為了壓低總價以迎合首購族,紛紛推出「小宅」的市場趨勢,加上單身戶與頂客族增加,家庭所需的基本空間也跟著減少。

有趣的是,雖然近年來「家庭總空間」變小,但個人空間卻變得更寬敞。1995年,台灣每人平均居住坪數僅9.43坪,但到了2025年已攀升至14.93坪。
30年間,每人居住坪數大幅增加58.3%,最大的推手是「少子化」與「家庭結構核心化」,因同住家庭人口數(分母)縮減速度,遠遠快過房屋總坪數(分子)變小速度,才造就了「家變小了,但個人空間變大」的情況。
另台灣人「有土斯有財」觀念根深蒂固。30年來,自有住宅率始終穩如泰山,1995年為83.56%,到了2025年依然維持83.95%的超高水準。相較於歐美許多先進國家自有住宅率僅約6成,台灣人對「買房」的執念,全球名列前茅。
值得注意的是,面對高房價,租屋族理應大幅增加,但數據卻給出相反的答案。家庭「租押(租屋)」比例從1995年的9.78%,一路緩跌至2025年的7.62%。顯示出即使房價高不可攀,多數台灣人若非仰賴長輩金援購屋或繼承家業,也極力避免長期租屋,寧可背負沉重的房貸,也要擁有一間屬於自己的「小宅」。
