Essential services refer to those services that are absolutely necessary for the survival and well-being of citizens. Some common synonyms for essential services include essential infrastructure, critical services, vital services, indispensable services, necessary services, and key services. These services include healthcare services, emergency services, food and water supply services, energy services, waste management services, and transportation services. They are crucial for maintaining public order, safety, and health, particularly during emergencies and natural disasters. Governments and communities rely on these services to provide a sense of security and stability, and to ensure that basic needs are met. Ensuring access to essential services is therefore a fundamental responsibility of governments and societies.
