The Term Administration, as used in the context of Government, Differs According to jurisdiction. The federal government of the United States is the national government or Administrative Government of the United States. It consists of 50 states, a federal district, five major self-governing territories, and several island possessions. The Administrative Map of the USA is divided into three distinct branches: legislative, executive, and judicial. The constitution of the USA defined the powers and duties of these 3 branches.
The primary or first-level administrative division of the United States is the state. Counties are the smaller administrative regions of the state. Every state has many counties. The District of Columbia (DC) is under the direct authority of Congress.
The United States Geological Survey (USGS), a scientific federal agency, produces several national series of topographic maps that vary in scale and extent, with some wide gaps in coverage. The largest (both in terms of scale and quantity) and best-known topographic series is the 7.5-minute or 1:24,000 quadrangle. This scale is unique to the United States,[citation needed] where nearly every other developed nation has introduced a metric 1:25,000 or 1:50,000 large scale topo map.
The USGS also publishes 1:100,000 maps covering 30 minutes latitude by one-degree longitude, 1:250,000 covering one by two degrees, and state maps at 1:500,000 with California, Michigan, and Montana needing two sheets while Texas has four.
