Sustainable Development Goal 3: Good Health and Well-Being

By Ansh vaishnava

1. Introduction

Sustainable Development Goal 3 (SDG 3) is one of the 17 Sustainable Development Goals adopted by the United Nations in September 2015 under the 2030 Agenda for Sustainable Development. Its main aim is to ensure healthy lives and promote well-being for all at all ages. It recognizes that good health is essential for individual development, social progress and economic growth.

Health is not limited to the absence of disease. It also includes physical, mental and social well-being. People need access to quality healthcare, nutritious food, safe drinking water, clean surroundings, vaccinations, health education and affordable treatment to lead healthy lives.

SDG 3 focuses on improving healthcare systems, reducing preventable deaths, controlling communicable and non-communicable diseases, promoting mental health, ensuring reproductive healthcare and making essential health services accessible to everyone.

The goal emphasizes equity in healthcare, meaning that access to health services should not depend on a person’s income, gender, age, disability or geographical location. It also recognizes that the health of individuals is closely connected with other development goals, including poverty reduction, nutrition, clean water, sanitation, sustainable cities and environmental protection.

2. Objectives of SDG 3

The major objectives of SDG 3 are:

  1. Reduce maternal and child mortality: Prevent deaths during pregnancy, childbirth and early childhood through timely medical care.
  2. Control communicable diseases: Prevent and treat diseases such as tuberculosis, HIV/AIDS, malaria and other infectious diseases.
  3. Prevent non-communicable diseases: Reduce premature deaths caused by conditions such as cardiovascular diseases, cancer, diabetes and chronic respiratory diseases.
  4. Promote mental health: Improve awareness, early identification and access to mental health support.
  5. Achieve universal health coverage: Ensure that people can access essential health services without suffering financial hardship.
  6. Improve road safety: Reduce deaths and injuries caused by road traffic accidents.
  7. Ensure reproductive healthcare: Provide access to reproductive health information, services and family planning.
  8. Reduce environmental health risks: Minimize illness caused by air pollution, unsafe water, hazardous chemicals and other environmental hazards.
  9. Strengthen healthcare infrastructure: Improve health facilities, medical equipment, medicine availability and the healthcare workforce.
  10. Improve emergency preparedness: Strengthen the ability of health systems to respond to epidemics, pandemics and other health emergencies.

These objectives form the foundation of the goal’s 13 targets.

3. Targets of SDG 3

SDG 3 contains 13 targets, numbered 3.1 to 3.9 and 3.a to 3.d. These targets cover specific health outcomes, access to services and the systems needed to improve public health.

TargetDescription
3.1: Maternal healthBy 2030, reduce the global maternal mortality ratio to less than 70 deaths per 100,000 live births. This requires antenatal check-ups, skilled birth attendants, emergency obstetric care and postnatal services.
3.2: Newborn and child healthEnd preventable deaths of newborns and children under five. The targets include neonatal mortality of no more than 12 deaths per 1,000 live births and under-five mortality of no more than 25 per 1,000 live births.
3.3: Communicable diseasesEnd epidemics of AIDS, tuberculosis, malaria and neglected tropical diseases, while combating hepatitis, waterborne diseases and other communicable diseases.
3.4: Non-communicable diseases and mental healthReduce premature mortality from non-communicable diseases by one-third through prevention and treatment, and promote mental health and well-being.
3.5: Substance-use prevention and treatmentStrengthen the prevention and treatment of substance-use disorders, including drug abuse and the harmful use of alcohol.
3.6: Road safetyThe original 2030 target was to halve global deaths and injuries from road traffic accidents.
3.7: Sexual and reproductive healthcareEnsure universal access to sexual and reproductive healthcare services, family planning, information and education.
3.8: Universal health coverageAchieve universal health coverage, including financial risk protection, access to quality essential healthcare and safe, effective, affordable essential medicines and vaccines.
3.9: Environmental healthSubstantially reduce deaths and illnesses caused by hazardous chemicals, air pollution, water pollution and soil contamination.
3.a: Tobacco controlStrengthen implementation of the World Health Organization Framework Convention on Tobacco Control.
3.b: Medicines and vaccinesSupport research and development of vaccines and medicines, improve access to affordable essential medicines and vaccines, and address diseases affecting developing countries.
3.c: Healthcare workforceIncrease health financing and the recruitment, development, training and retention of healthcare workers, particularly in developing countries.
3.d: Health emergency preparednessStrengthen early warning, risk reduction and management of national and global health risks.

Understanding the targets

These targets can be understood through three broad areas:

  • Improving health outcomes: Targets 3.1 to 3.7 focus on preventing deaths, controlling diseases, improving maternal and child health, and promoting mental and reproductive health.
  • Making healthcare accessible: Target 3.8 focuses on universal health coverage, while 3.b and 3.c support affordable medicines, vaccines and a trained healthcare workforce.
  • Building a resilient health system: Targets 3.a, 3.9 and 3.d address tobacco control, environmental risks and preparedness for health emergencies.

Together, these areas aim to create a healthcare system that prevents illness, treats disease effectively and protects people throughout their lives.

4. Importance of SDG 3

A. Improvement in quality of life

Good health enables people to participate in education, employment, family life and community activities. Preventive healthcare, timely diagnosis and treatment can reduce avoidable suffering and improve life expectancy.

B. Reduction in poverty and inequality

Serious illnesses can force households to spend a large portion of their income on treatment or lose earnings when family members cannot work. Affordable healthcare and financial protection can reduce this burden, particularly for low-income households.

C. Maternal and child welfare

Access to maternal care, skilled birth attendance, immunization, nutrition and newborn services improves the chances of healthy pregnancies and childhood development. These interventions are particularly important in underserved rural and urban communities.

D. Economic development

A healthy population can contribute more effectively to the economy. Better health reduces preventable absence from work and school, supports productivity and reduces the financial pressure associated with avoidable medical treatment.

E. Disease prevention and emergency preparedness

Strong public health systems help detect outbreaks, provide timely treatment and communicate risks to communities. Surveillance, vaccination programmes and emergency planning can reduce the impact of infectious diseases and other health threats.

F. Environmental sustainability

Air pollution, contaminated water, poor sanitation, unsafe housing and exposure to hazardous substances can contribute to disease. SDG 3 therefore connects healthcare with environmental management, sanitation, housing and sustainable urban development.

5. Major challenges in achieving SDG 3

Despite progress in healthcare, several challenges continue to affect its achievement by 2030.

  1. Unequal access to healthcare: Rural, remote and underserved urban communities may lack nearby facilities, specialists, medicines or diagnostic services.
  2. High healthcare costs: Out-of-pocket expenditure can place significant financial pressure on households, especially when treatment requires hospitalization.
  3. Shortage of trained professionals: Uneven distribution of doctors, nurses, specialists and other healthcare workers can reduce the quality and availability of care.
  4. Communicable diseases: Tuberculosis and other infectious diseases continue to require sustained prevention, diagnosis, treatment and public awareness.
  5. Non-communicable diseases: Cardiovascular diseases, diabetes, cancer and chronic respiratory diseases create a growing need for prevention and long-term care.
  6. Mental health concerns: Stigma, limited awareness and inadequate access to trained professionals can prevent people from seeking support.
  7. Environmental pollution: Poor air quality, contaminated water, inadequate sanitation and unsafe waste disposal contribute to health risks.
  8. Road traffic injuries: Unsafe roads, insufficient pedestrian facilities and inadequate road-safety measures expose people to preventable injuries.
  9. Emergency preparedness: Disease outbreaks, climate-related disasters and other emergencies can disrupt essential healthcare services.
  10. Data and monitoring gaps: Incomplete or outdated health data can make it difficult to identify vulnerable populations and allocate resources effectively.

These challenges show that healthcare improvement requires not only medical services but also coordinated action across government departments, communities and planning institutions.

6. Strategies to achieve SDG 3

The following measures can help governments, local authorities and communities make progress towards the goal.

  • Strengthen primary healthcare: Improve local health facilities, diagnostic services, medicine availability and preventive care so that people can receive treatment before conditions become severe.
  • Increase public health awareness: Promote health education, vaccination, nutrition, physical activity, disease prevention and mental well-being.
  • Improve financial protection: Expand appropriate health coverage and reduce the financial barriers that prevent people from obtaining essential treatment.
  • Focus on vulnerable populations: Prioritize maternal and child health, older adults, persons with disabilities, low-income households and underserved communities.
  • Integrate health into urban planning: Consider health impacts when planning roads, housing, public spaces, industrial areas, sanitation systems and transport networks.
  • Promote road safety: Improve junction design, traffic management, pedestrian crossings, footpaths, cycling facilities and enforcement of road-safety regulations.
  • Reduce environmental risks: Control pollution, improve waste management, ensure safe drinking water and strengthen sanitation infrastructure.
  • Strengthen healthcare personnel: Improve training, recruitment, retention and the distribution of health workers, especially in underserved areas.
  • Use technology and data: Apply GIS mapping, health information systems and spatial analysis to identify service gaps, monitor disease patterns and support evidence-based decisions.
  • Improve emergency preparedness: Strengthen disease surveillance, early-warning systems, emergency response plans and the resilience of healthcare facilities.

7. Monitoring and indicators of SDG 3

Progress towards SDG 3 is measured through indicators that assess health outcomes, healthcare access and the capacity of health systems. The United Nations maintains the official SDG indicator framework, while the World Health Organization provides health-related data and monitoring resources.

IndicatorWhat it measures
Maternal mortality ratioMaternal deaths per 100,000 live births
Neonatal mortality rateDeaths during the first 28 days of life per 1,000 live births
Under-five mortality rateDeaths before the age of five per 1,000 live births
Communicable disease indicatorsMeasures relating to HIV, tuberculosis, malaria and other specified diseases
Premature mortality from non-communicable diseasesRisk of dying prematurely from specified major non-communicable diseases
Universal health coverageAccess to essential health services and related financial protection
Road traffic mortality rateDeaths resulting from road traffic injuries
Environmental health indicatorsDeaths and illnesses associated with air, water and other environmental pollution
Health workforce indicatorsAvailability and distribution of healthcare professionals
Emergency preparedness indicatorsCapacity to detect and manage health emergencies

8. Conclusion

Sustainable Development Goal 3 is essential for achieving sustainable development because health influences every aspect of human life, including education, employment, economic security and social participation. Its focus extends beyond treating illnesses to preventing disease, promoting mental well-being, protecting mothers and children, reducing environmental health risks and ensuring access to affordable, quality healthcare.

Achieving SDG 3 by 2030 requires coordinated efforts from governments, healthcare institutions, local authorities, communities and individuals. For urban and regional planners, this means designing settlements that provide equitable access to healthcare, safe mobility, clean environments, sanitation and recreational spaces.

Ultimately, a healthy population is both a foundation and an outcome of sustainable development. Progress towards SDG 3 depends on building communities in which everyone has a fair opportunity to live a healthy and fulfilling life.

Good Health and Well-being (SDG 3): Ensuring Healthy Lives and Promoting Well-being for All at All Ages

The third Sustainable Development Goal (SDG 3) — Good Health and Well-being — aims to ensure healthy lives and promote well-being for all at all ages. Health is central to human development and a cornerstone of sustainable growth. Without good health, individuals cannot access education, participate in the workforce, or contribute effectively to society. SDG 3 recognizes that achieving global health requires more than disease prevention; it encompasses a holistic approach that includes physical, mental, and social well-being.

Although the world has made remarkable progress in improving health outcomes over the past few decades — such as reducing child mortality, eradicating certain infectious diseases, and extending life expectancy — inequalities in access to healthcare and health outcomes remain stark. The COVID-19 pandemic, in particular, exposed the fragility of health systems worldwide and reversed years of progress in several regions. Achieving SDG 3 by 2030 requires resilient, equitable, and inclusive healthcare systems that leave no one behind.

Understanding SDG 3

SDG 3 builds upon the foundation of previous global health initiatives, such as the Millennium Development Goals (MDGs), which focused on child mortality, maternal health, and combating major diseases like HIV/AIDS and malaria. The 2030 Agenda expands this vision, adopting a more comprehensive approach to health that addresses both communicable and non-communicable diseases, mental health, universal health coverage, and environmental health risks.

The overarching goal of SDG 3 is to promote health equity — ensuring that every individual, regardless of gender, income, or geography, can lead a long and productive life. The World Health Organization (WHO) emphasizes that health is not merely the absence of disease but “a state of complete physical, mental, and social well-being.”

Targets of SDG 3

The United Nations has outlined several targets to guide progress toward achieving good health and well-being by 2030:

  1. Reduce global maternal mortality to less than 70 per 100,000 live births.
  2. End preventable deaths of newborns and children under five years of age.
  3. End the epidemics of AIDS, tuberculosis, malaria, and neglected tropical diseases, and combat hepatitis, water-borne diseases, and other communicable diseases.
  4. Reduce premature mortality from non-communicable diseases (NCDs) through prevention, treatment, and promotion of mental health and well-being.
  5. Strengthen the prevention and treatment of substance abuse, including narcotic drug abuse and harmful use of alcohol.
  6. Halve the number of global deaths and injuries from road traffic accidents.
  7. Ensure universal access to sexual and reproductive health services, including family planning and education.
  8. Achieve universal health coverage (UHC), including financial risk protection and access to quality essential healthcare services.
  9. Reduce deaths and illnesses from hazardous chemicals and pollution.

These targets reflect a broad commitment to addressing health challenges through prevention, treatment, and systemic reform.

Global Progress and Challenges

Significant progress has been made since 2000. Global child mortality has declined by more than half, and maternal mortality has also dropped substantially. The global HIV epidemic has been slowed through awareness, prevention, and treatment programs. Vaccination campaigns have nearly eradicated diseases like polio in most regions.

However, major challenges remain. Non-communicable diseases (NCDs) — such as heart disease, cancer, diabetes, and respiratory illnesses — now account for over 70% of all global deaths. Mental health disorders, including depression and anxiety, have emerged as silent epidemics. The COVID-19 pandemic further strained healthcare systems, disrupted routine immunization programs, and widened health inequities.

Additionally, access to healthcare remains deeply unequal: in low-income countries, millions still lack access to essential medicines, skilled birth attendants, and basic sanitation. Environmental hazards, pollution, and climate change are now major determinants of public health, causing millions of premature deaths annually.

Strategies for Achieving SDG 3

  1. Strengthening Health Systems and Universal Health Coverage (UHC)
    Achieving SDG 3 requires robust health systems capable of providing affordable, quality care for all. Governments should invest in infrastructure, digital health solutions, and health workforce development. Universal health coverage ensures that no one faces financial hardship when seeking care.
  2. Preventing and Controlling Diseases
    Effective disease surveillance, vaccination, and early detection systems are vital. Integrated healthcare approaches should address both communicable and non-communicable diseases simultaneously, especially in resource-limited settings.
  3. Promoting Healthy Lifestyles
    Encouraging physical activity, balanced diets, and the reduction of tobacco and alcohol use are key preventive strategies. Public health campaigns and school-based health education can promote lifelong healthy behaviors.
  4. Improving Maternal and Child Health
    Access to antenatal care, skilled birth attendants, and neonatal services are essential. Investments in nutrition, breastfeeding promotion, and immunization programs significantly reduce child mortality.
  5. Addressing Mental Health
    Mental health must be integrated into primary healthcare systems. Reducing stigma, expanding access to counseling and psychiatric care, and promoting community-based mental health programs can save lives and improve well-being.
  6. Environmental Health and Climate Resilience
    Air pollution, unsafe water, and exposure to hazardous chemicals are major health risks. Policies that promote clean energy, sustainable transport, and climate resilience also advance public health goals.
  7. Global Cooperation and Health Equity
    International collaboration is vital for tackling pandemics, sharing research, and ensuring equitable access to vaccines and medicines. Strengthening the role of WHO and cross-border health partnerships will enhance global preparedness.

Case Studies and Best Practices

Countries such as Thailand and Rwanda demonstrate that universal health coverage is achievable even in lower-income settings through strong political will and community-based models. Rwanda’s community health insurance program, for example, has significantly improved maternal and child health outcomes. Similarly, Thailand’s universal healthcare scheme has reduced inequality in health access and improved life expectancy.

The Way Forward

The pursuit of SDG 3 requires a multi-sectoral approach that integrates health with education, environment, economy, and governance. Governments must increase health budgets, enhance data-driven decision-making, and promote preventive care. Civil society and private sectors play critical roles in innovation, financing, and outreach. Moreover, empowering communities to participate in health planning ensures that interventions are locally relevant and sustainable.

Conclusion

Good Health and Well-being (SDG 3) embodies the universal right to health — a right that is essential for human dignity and global prosperity. Achieving this goal by 2030 demands equitable access to healthcare, investment in prevention, and the strengthening of public health systems worldwide.

A healthy population is the foundation for all other Sustainable Development Goals. As nations recover from the COVID-19 crisis and confront new health challenges, the world must reaffirm its commitment to building resilient, inclusive, and people-centered health systems that safeguard well-being for current and future generations.
