According to the Las Vegas Review Journal:

“About 21,000 Nevadans had bought and paid for coverage as of Saturday (3/8/2014). The exchange is enrolling as many as 1,000 customers a week; at that pace, sign-ups could max out at around 25,000 on March 31 (Deadline). That’s 21.2 percent of the exchange’s original target of 118,000, and half of a revised goal of 50,000.”
