According to, about 5.5 million. There are approximately six million baptized members of the Church of Jesus Christ of Latter-day Saints (commonly called the "mormon" church) in the United States. This is about 40% of the total Church membership worldwide, which is near 14 million.
You can explore a map illustrating how Mormon Church membership is distributed in an interactive map, which can be found at the "related link" below.
This is a ridiculous question to answer, because there are over 200 countries in the world. So I am going to refer this question to this website: Wikipedia

By number and by percent of total population, Rhode Island has the lowest Mormon population with 3,700 baptized members of the Church of Jesus Christ of Latter-day Saints (the "Mormon" church) That is 0.4% of the population. That is a tie with Connecticut, where 0.4% of the population is Mormon. Other states with the lowest Mormon populations are also in New England, including Maine 0.8%, New Hampshire 0.6%, Vermont 0.7%, and Maryland 0.7%.
Contrast that with states in the west:
Utah 68% Mormon, California 2%, Washington 4%, Idaho 27%, and Nevada 7%.
Most recent record I've heard is approximately 13.6 million.

The Church of Jesus Christ of Latter-day Saints (the "Mormon" church) does not release membership statistics for an area smaller than a state, so it is impossible to know the exact Mormon population of a city or town. However, there are many small towns in Utah in which 95-100% of the population are baptized Mormons.
