The Church recently released a new beta version of its Newsroom site. It includes lots of statistics and information about several countries and each state in the U.S. Here is some info on Nevada:
In 1852, three years after the discovery of gold in California, seven members of The Church of Jesus Christ of Latter-day Saints (Mormon church) established a trading post in what is now Genoa (near Lake Tahoe)…. In 1855, 30 men were called to establish a mission at the Meadows in southern Nevada…. In the late 1920s, many Utahns moved to Nevada in search of better economic conditions. The Las Vegas Nevada Temple was dedicated in 1989 as “an oasis of peace and light.”
The Reno temple was dedicate in April 2000. Of the 2.4 million people in Nevada, 167,822 are Mormons (6.9%). Nevada has 2 missions, 2 temples, 5 family history centers, and 304 congregations (ward/branches).
