Shrinking populations are problematic due to the inverted age structure, with more old people than young.
When that happens, there won't be enough workers in the future to support the elderly, and there may be an increased demand for health and social care.
But experts say China's situation could be uniquely exacerbated given the number of men who are finding it difficult to find a wife in the first place, let alone think of starting a family.
After all, there is a severe gender imbalance in the country - last year, there were 34.9 million more males than females.
