Global
The world population is expected to touch 8.5 billion by the end of this decade.
While Asia is expected to be overpopulated, Europe, it is said, will be underpopulated.
Due to falling fertility levels and rising longevity, the future population could have a higher number and share of older people.
Thus, the two significant transformations are expected to be an imbalanced distribution of the population across regions and a skewed age structure
The population today is more centred in urban areas.
By 2030, it is estimated that two-third of the people will inhabit urban spaces, which will put a strain on infrastructure and amenities.
This, in turn, could compromise the quality of life of urban citizens.
Focus on Women's Health
The theme of this world population day is ‘women’s sexual and reproductive health and reproductive rights’, marking the 30th anniversary of the International Conference on Population and Development (ICPD).
This gives us an opportunity to accelerate efforts to realise the ICPD’s programme of action.
While there has been reasonable progress in three decades — women have greater access to modern contraceptives today and maternal deaths have declined considerably since 2000 — there are still unequal results across regions.
It is unacceptable that each day, 800 women die globally from preventable causes relating to pregnancy and childbirth.
A disproportionate share of these deaths occur in developing countries.
Reduced maternal mortality levels need to be associated with reduced fertility levels because lower fertility reduces exposure to maternity.
However, decline in fertility levels is also associated with delayed childbearing among women.
Migration & Urbanisation
The distribution of the population in the future will continue to be shaped by migration.
In recent decades, we have seen greater mobility of people.
People often migrate due to poor development and infrastructure in their regions.
A study estimates that 60 crore Indians migrate within the country annually, and 2 crore migrate abroad.
Given the potential of India’s future urbanisation, it is important to encourage the emergence of new cities in order to release pressure on existing mega cities.
These need to have the same kinds of infrastructure and public amenities as the mega cities.
It is clear that cities are the drivers of the global economy. At present, 600 urban centres drive 60% of the world’s GDP.
An assessment of global cities by Oxford Economics resulted in the Global Cities Index, which ranked the top cities in the world based on five categories: economics, human capital, quality of life, environment and governance.
This exercise evaluates the urban quality of life, which needs to be studied so that the trends of rapid urbanisation and growing migration can be understood.
Most projections of India’s population are based on decades-old data.
Until India conducts its census, we will only have estimates.
It is important to know the exact count and the demographic makeup so that we can draft better policies.
Despite more countries adopting stringent immigration policies, more Indians will continue to emigrate, at least in the near future.
At the same time, India needs to seriously prepare its workforce for the global labour market.
