In 2005, both cities hosted the same number of international conferences with 27 events after a decrease of 8 and 3 events in city A and city B respectively from 1980 to 2005. By the year 2010, conferences hosted in city B had overtaken the number in city A and reached to 26. Meanwhile, there was a decline of 3% in the number of conferences hosted in city A, ending at 24.
