GLOBAL POPULATION DYNAMICS, FERTILITY PATTERNS AND INDIA

 GLOBAL POPULATION 

Sincere Country wise estimate of population showed that in 2025 India's elevated position as the largest populated country with an estimated population 1,463,865,525 people,  was followed by China with 1,416,096,094,USA 347,275,807 and Indonesia 285,721,236.As per the  2025 estimate of  world population projected amounts to 8.2 billion (8226,758,730).While total fertility rate for India is estimated as 2.01 it is only1.18 for China and 1.66 for USA. Globally despite growth  in population  has slowed  down but the  disparities between high income and low income countries still persists.Understanding demographic changes are vital for developing social and economic infrastructure , health planning, welfare pension planning and budgetary allocations. UNFPA (United Nations Fund for Population Activities) report on the State of world population examined the state of bodily autonomy and reproductive choice across the globe. The study is  mainly  based on data  collected from fourteen countries examining their reproductive lives and futures .Reproductiv choice is more than just freedom from coercion or improved access to services, which is full range of conditions that enable people to exercise  their reproductive rights and ensure true choice, including gender equality, decent health and confidence in the  future. The study found that these  concerns are directly intensifying anxiety over declining fertility rates, increasing ageing and workforce shortage across the globe. In reality the study found that only very  few  people  are able to realize those ambitions. Apart from declining fertility rates ,ageing and shortage of adequate workforce many people still argue that the greatest threat is overpopulation. Recent studies on fertility also brought out that generally about half of the pregnancies are unintended. Earliier studies also indicated 10% women were  unable to make true choices.Media,academics and policy makers  presume that fertility decline is an issue of female choice and women are unreliable reporters of  their own internal desires .Data indicated that while women in  Japan and South Korea are increasingly opt out of marriage women in Italy,Netherlands, and Latin America opt against motherhood. But the fact also  remains that women are seldom able to exercise their reproductive choice. In any case availability of modern contraceptive options and increasing sexuality  education and awareness made significant progress towards women's reproductive rights. 

POPULATION DYNAMICS IN INDIA 

India's population reached  146.39 crores in April 2025 and is expected to reach 170 crores around 40  years and projected to  decline after reaching the Peak  level per UNFPA report Total Fertility Rate (TFR) dropped to 1.9 well below the replacement level.  Currently 68% of India's population belong to  the working- age group (15-64) presenting both  a unique opportunity in terms of "demographic dividend" and a great challenge in terms of  education Skilling, research, innovations and generating adequate employment. TFR of  2.1,which means that average Indian women are having fewer children than what is required to sustain the population size across generations.In other words India has made rapid progress in lowering fertility from nearly five children per woman in 1970 to about two today. This has led to substantial reductions in  infant mortality and maternal mortality rates. Report also calls for addressing unmet reproductive rights and the issue that millions of people are unable to realise their fertility goals.According to  the report 36% adult Indian women face unintended pregnancies as against 30% experience unfulfilled desire  for having either more or fewer children and specifically 23% face both issues. Even after reaching replacement level  of fertility (generally defined as 2.1 berth per woman, many women particularly contiue to face strong barriers  to make free and informed decisions their reproductive lives with significant disparities across different  states and Union Territories. States  like Bihar(3.5),Uttar Pradesh (3.1)and Jharkand (2.7) continue to experience high fertility rates as against Kerala (1.5),Delhi (1.4),West Bengal(1.4)  Tamil Nadu(1.4),Maharashtra (1.5) Andra Pradesh (1.5) and Jammu and Kashmir (1.5 ) indicated  sustained below- replacement level fertility rates. This duality can be attributed to divergences in economic opportunities ,access to health care, educational level and prevailing gender and social norms and cultural factors. More specifically educational status of women, access to family planning services and  economic development directly impacted fertility. 

UNFPA 's online poll conducted across 14 countries including India covering 14000 respondents found that nearly 40% of them reported that financial limitations is the biggest barriers stopping them from having the families they want.Other barriers are job insecurity (21%),housing constraints (22%) and lack of reliable child care facilities(18%). Health barriers like poor living conditions and low well-being (15%),infertility (13%),and poor access to pregnancy related care (14%) are other distressing factors. While 19% faced either partner or family pressure to hav fewer children than they personally desired,many are also holding back due to growing anxiety about future- from climate change to geo political conflicts and social instability. 

CONCLUSION 

Beyond traditional barriers  emerging social realities  are reshaping fertility. The  study found that global fertility rates are declining. Human population is projected to reach it's  crest within the century and afterwards expected to fall. There is vast  demographic diversity across countries. While some continue to experience high fertility rates, others have declining fertility.Similarly both high fertility rates and  declining fertility rates  may encourage or discourage internal and international migration. India has made rapid progress in lowering fertility rates  from five  children per woman in 1970 to two today due to improved education and access to reproductive health care. Consequentlly country witnessed rapid reductions in infant mortality ,maternal mortality and improved health conditions of  mothers. However deep inequalities still persist across states ,Castes,and income groups. UNFPA vision for India called for a right based "demographic resilience " wherein societies' ability to adopt to population change without sacrificing human rights are emphasised. This right based approach mainly depends on - 1.expanding sexual reproductive health services with universal access to contraception, safe abortion, maternal health and infertility care. 2. Removing structural barriers by investing in Child care,education, housing and flexibility in workplace 3.Promoting inclusive policies extending services to unmarried individuals and other marginalised groups 4.Improving data and accountability beyond fertility rates to measure  unmet family planning needs and bodily autonomy. and 5.Fostering social change through community initiatives  challenging stigma and building health literacy. United Nations  mission to deliver a world where every pregnancy is wanted every  child birth is safe and every young person's potential is fulfilled. Infact realization of reproductive rights and access to wide range of reproductive and supportive health services including quality maternal and child care can contribute to healthy reproductive outcomes.
