There is no answer to this question! Roller coasters are built all the time, around the world!
California in 1934
According to Roller Coaster Database (www.rcdb.com) there are 3364 roller coasters in the world, 768 of which are in North America. But those numbers change every time a coaster is built or demolished, which can happen quickly.
The first roller coaster was actually a coal mining car in NY in 1895 that ran 18 miles down hill and would hit a 100 MPH. People came up to the hill where it was located and rode it down. Roller coasters became popular after WW1 and there were over 2,000 built in the United States in the early 1900's. In 1927 the Coney Island roller coaster opened. The early roller coasters were very dangerous and many people got hurt on them. They are called roller coasters because wheels are used for them to coast on a track. It is all done with gravity.
It is believed that the first roller coasters were built in the late 18th to early 19th centuries in Russia and France. These coasters were based on "Russian Mountains", sled rides on hills of ice. The first modern roller coaster was patented in 1872 by John G. Taylor. A ride based on his design was built at the now-closed Savin Rock in West Haven, CT
The 1980's.
Roller Coasters originated from ice slides that were built in Russia in the 1400's.
