The legal definition of essential services can vary depending on local laws and regulations. In general terms, essential services are typically defined as those necessary to maintain basic societal functions or ensure public health and safety. The specific criteria used to determine which businesses qualify as essential may vary by jurisdiction. Governments may consider factors such as vital infrastructure maintenance (water supply systems, power grids), provision of essential goods (food production and distribution), healthcare services (hospitals, clinics), emergency response capabilities (fire departments), law enforcement agencies (police forces), transportation networks (airports, railways) among others.
