Public administration in Israel at the federal level is performed by 28 primary ministries. Ministries provide a range of services, including traditional public goods such as national defense, as well as functions unique to Israel, such as maintaining relations with the Jewish Diaspora. Historically, public expenditures have been concentrated in the defense, education, employment and healthcare sectors. Local governments share responsibility for secondary schools, local healthcare, waste management, road maintenance, parks and local emergency services.
