Regions maintain no government. Also, a region is a geographic area with very loosely defined boundaries. For example, we might refer to the Rocky Mountain region, which generally is thought to include those geographic areas that are in fairly close proximity to the mountain range. The difference is that one particular town maybe just outside of or included in the "region" at different points and for different purposes. Again, there is no clearly depicted boundary or legal description that includes a certain location in a region. Generally, a region is larger than the other two entities you ask about, and is more amorphic (without shape/boundary). There is no official governing body for a region, and residents are not subject to a uniform code of law. A region has no citizens, only residents. Residents may reside in a variety of cities, counties, states, and be citisens of those entities, but are not subject to any law other than to the laws of the land with ogverning bodies (their country, state, county, city, township, etc.)
A state (e.g., Colorado) has clearly defined geographic boundaries and has certain laws and systems of law-making that define those boundaries, as well as laws that prescribe legal and illegal actions of its residents and geographic properties. States have governing bodies. State laws may not eclipse the broader laws of the country in which it exists. Often, but not always, states impose taxes, but they make and repeal law, and have a body of government. Frequently states have some form of a governing constitution.
Counties (e.g., Grand County, CO) are entities that reside within a state. They govern an even smaller scope of people and usually, real properties. Counties do not exist outside a state, and counties do not maintain their own consitution of law, although they may pass ordinace/law. Counties do also form governments, but those governments are beholden to state laws, and to the laws of the country in which those states exist, as well. Counties do not make broadly governing laws applicable outside of their jurisdiction; instead, they make a smaller subset of law called ordinances, a legal term. Counties are generally the smallest of the three enitities in terms of population, but that is not a mandaotry condition to being named a county. Counties also serve as smaller entities that serve the enforcement of state and federal laws, as well as their own ordinances.
I hope that helps you.
