India's total fertility rate just dropped to 1.9, below the 2.1 replacement level, according to NFHS-6 data released this month. Delhi is already at 1.2. Population won't decline tomorrow - we have enough young people to sustain momentum for 20-30 years - but the long-term direction is set.
Japan hit this turning point in the 1970s. Here is what followed over the next 40 years:
Japan's population has been shrinking for 16 consecutive years. Today, over 9 million homes sit vacant - 13.8% of all residences - a phenomenon known as "akiya" (abandoned homes). By 2033, projections say 1 in 3 Japanese homes will be empty. In rural and small-city Japan, property values have collapsed. But Tokyo and Osaka are still rising, because everyone who wants work or a decent life is concentrating there.
The pattern is not uniform collapse - it is polarisation. Urban cores with jobs, hospitals, and transport hold or appreciate. Peripheral areas built on population-growth assumptions face long-term demand erosion.
Now apply that to India. A lot of peripheral real estate - suburban townships 30-50 km from city centers, sold on future metro connectivity - is priced on the assumption of steady household formation growth. If TFR stays at or below 1.9, household formation will plateau and then contract. The demand that was supposed to absorb those units in 2040-50 may simply not materialise.
This does not mean Indian real estate is about to crash. But it does raise a question no developer is asking out loud: are buyers of peripheral plots today being sold a 20-year story that demographics may not support?
Would be curious if others think India can avoid the Japan trajectory, or if the urban vs peripheral split is already starting here.
