There are 3 levels of government in the U.S.: federal, state, and local. All levels of government must obey the U.S. and State Constitutions. The U.S. Constitution gives the federal government certain powers and assigns all other powers to the state governments. State governments establish the local governments within their territories and delegate certain powers to them.
Each level of government is divided into 3 branches: the legislative branch (makes the laws), the executive branch (carries out the laws), and the judicial branch (applies the laws to specific court cases and interprets the laws).
The federal government produces currency, regulates taxes, establishes federal welfare programs and foreign policy. It oversees the defense of the country and makes laws that affect the nation as a whole. The federal government ensures cooperation of state and local governments by providing funds to operate federal programs, such as affordable health insurance, building roads, airports, highway systems, and pollution control.
The state government oversees affairs within state borders. It raises income taxes and oversees state welfare programs, such as Medicaid. It also controls the state criminal code, maintains state roads, and carries out federal laws and programs at the state level. State and local courts hear cases and interpret the state constitution and laws. State and local governments work together to operate schools and ensure they meet state standards.
Local Government – Counties/Cities & Towns. States are divided into areas which carry out state laws within a specific geographic location. Cities, town, and counties are granted specific powers by the state. In Virginia, counties and cities are separate units, independent of each other. However, towns are part of a county. Citizens of each county, town, or city elect representatives to govern them. A county has a board of supervisors. Towns or cities have mayors and councils to oversee the delivery of public services. Local government responsibilities include managing most public services, such as parks, libraries, schools, police, and fire services. Local governments solve common problems, such as funding police and fire departments and education. They also work to lessen air pollution
