(b) Only two statements are correct (1st and 2nd)
An ageing population can indeed lead to an increased dependency ratio, with fewer working-age individuals supporting a larger elderly population.
Japan, Italy, and Germany are among the countries with the highest percentages of elderly citizens.
An ageing population often results in higher healthcare and pension costs, putting financial strain on government budgets.
The ageing population problem is not limited to developed countries; it is increasingly becoming a concern for developing countries as well, due to rising life expectancy and declining birth rates in many regions. (Statement 3 is incorrect)
As of 2022, the elderly population in India was 10.5% of the population, or 149 million people aged 60 or older. The United Nations Population Fund projects that by 2050, the elderly population will double to 20.8% of the population, or 347 million people. This means that by 2046, the number of elderly people in India will surpass the number of children aged 0–14 years.
