Answer:
When the people of a territory or a region thereof have grown to a sufficient population and make their desire for statehood known to the federal government, in most cases Congress passed an enabling act authorizing the people of that territory or region to frame a proposed state constitution as a step toward admission.The following is a rough guide to the process: Generally, the U.S. Congress requires a certain minimum population. For example, when Michigan was applying for statehood in the 1830s, Congress required a minimum of 60,000 people to inhabit the territory applying for statehood. Congress can make a territory into a State at any time, without getting permission from anyone. Congress usually waits for a territory to request statehood. ... Typically, once Congress gets the request for statehood, they make some conditions for the new state.
