This table shows that, the different flat sizes along with living space per person in 1980s, 1990s and 2000s.
The average household size experienced a consistent drop throughout the period. It started at 4.6 persons in the 1980s, fell to 3.9 in the 1990s, and reached its lowest point at 3.4 in the 2000s.
A general contraction in flat size was also observed. For instance, the 4-room flat decreased in floor area from 105 sq m in the 1980s to 100 sq m in the 1990s, and further to 90 sq m in the 2000s. Similarly, the 5-room flat shrunk from 123 sq m to 120 sq m, and finally to 110 sq m over the same period. The 3-room flat followed this trend, moving from 69 sq m in the 1980s to 65 sq m in the 2000s (with data for the 1990s unavailable).
Despite the reduction in the size of the flats, the available living space per person typically rose, thanks to the significant decrease in household size.
The living space in the 4-room flat increased from 23 sq m in the 1980s to 26 sq m in the 2000s. A similar growth was recorded for the 5-room flat, rising from 27 sq m to 32 sq m over the three decades. The Executive flat, for which data is only available for the 1980s and 1990s, saw a modest increase from 32 sq m to 36 sq m. The 3-room flat also showed a substantial jump, going from 15 sq m in the 1980s to 19 sq m in the 2000s.
