The state governments follow the same pattern as the federal government, with power divided among the executive, legislative and judicial branches. In general, matters which lie entirely within state borders are the concern of state governments. These include internal communications; regulations relating to property, industry, business and public utilities; the state criminal code; and working conditions within the state.
ithin this context, the federal government requires that state governments not adopt laws that contradict or violate the Constitution or laws and treaties of the United States. There are many areas of overlap between state and federal jurisdictions. The federal government has assumed ever-broadening responsibility in matters relating to health, education, welfare, transportation, and housing and urban development. Programs in these areas are now often developed on a cooperative basis between the two levels of government.
