The federal government sets national policy on taxes, defense, immigration, Social Security, Medicare and interstate commerce, affecting virtually every American household.
It's the national government in Washington — the president, Congress, the courts and the agencies they oversee.
Public opinion often differs sharply between trust in the federal government and trust in state or local governments, which handle issues like schools, policing and roads.
Trust ratings can differ widely across federal entities, with the military and courts sometimes polling higher than Congress or specific federal agencies.
Congress writes laws, the president and executive agencies carry them out, and federal courts interpret them and resolve disputes about their meaning.
The federal government is financed primarily through income, payroll and corporate taxes, with spending levels set annually through the congressional budget and appropriations process.
Under federalism, Washington shares authority with the 50 states, with the Constitution and Supreme Court rulings defining which level of government has jurisdiction over specific issues.
