Dubai Gold Sales
The line graph shows estimated sales of gold in Dubai for 12 months in 2002 in millions of dirhams. There were two main seasons for gold sales.
The main season for sales is in the December to May period. Sales were consistently above 200 million dirhams per month, rising sharply to a peak of 350 million dirhams in March. However, for the next four months, sales declined steadily, reaching an annual low of 120 million dirhams in July.
In August, there was a sudden increase. Sales almost doubled, rising from 120 million dirhams in July to 210 million dirhams in August. This was followed by for the salea drop in September, the July figure.
From September to October, sales recovered, from 120 to 180 million. In October and November, sales remained steady, and there was a small increase in December to 190 million dirhams. 
In conclusion, the main sales period is in the early part of the year, slumping in the summer, except for a sudden increase in August.
Dubai Tourism, 1990-1994
The graph shows the numbers of tourists in hundreds of thousands visiting Dubai between 1990 and 1994. There are several features in the graph.
First of all, the total number of tourists increased rapidly between 1990 and 1994. In 1990 there was a total of 450,000 tourists in Dubai. This rose sharply to 625,000 in 1991, an increase of more than 30%, and rose slightly again to just under 700,000 in 1992. In the following two years, the number of visitors started to pick up again and reached 1 million in 1994. This was more thandouble the figure for 1990.
The second trend is that there was a huge increase in the number of tourists from Russia. In 1990, Russian tourists comprised only 20,000 or less than 5% of visitors. This number shot up to 50,000 in 1991 and doubled again to more than 100,000 in 1992. Between 1992 and 1994, the number trebled, from 110,000 to 330,000. This meant that Russian tourists made up one-third,or 33%, of Dubai’s 1 million visitors in 1994. In comparison, the number of tourists from other countries increased only slightly, from 550,
000 in 1991 to 580,000 in 1994.
In conclusion, although the number of tourists from all countries is increasing, Russian tourists are becoming more and more important for the tourism industry in Dubai.
North American Fish Catches
The graph shows changes in fish catches for the US and Canada over the last 30 years.
The most significant feature is that fish catches have declined drastically in both the US and Canada since the mid-1980s. Although Canadian production is much lower, its echoes US figures, declining or increasing at the same rate.
Between 1972 and 1977, US fish catches averaged between 2.5 and 2.75 million tonnes per year, while Canadian landings fluctuated between 800,000 and 1.1 million tonnes. In 1997, however, there was a big increase in fish caught in the US, and this rise continued up to a peak of 5.5 million tonnes in 1987. During the same period, Canada’s catch increased from 1 million tonnes to 1.5 million tonnes, an increase of 50%.
From 1987 onwards, there was a sudden decline in both countries. US figures tumbled to 4 million tonnes in 1995, a drop of 28%, and Canadian catches plunged to 0.5 million tonnes, a drop of 66%. In the following four years, US catches fluctuated around the 4 million tonne mark, while Canadian catches rose very slightly.
In general, both Canadian and the much larger US catch have declined dramatically since their peak in the mid-1980s.
