The bar chart below gives information about the percentage of the population living in urban areas in different parts of the world. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The graph illustrates the number of foreign tourists to different parts of the world in 15 years: from 1990 to 2005. 70 million people travelled to North America in 1990, and reached its peak at slightly more than 90 million. By 2005, the figures somewhat declined less than 90 million, maintaining the region as the most popular tourist destination. Also increasing but at a much faster rate is Central and Eastern Europe. Starting at around 30 million, the numbers dramatically increased up to 90 million after 15 years. Both regions had the most tourist arrivals, but they followed different growth patterns. While North America kept rising and reached its peak in 2000, and then gradually slowed down in the next five years, Central and Eastern seem to have had a more dramatic increase during the first and the last five years. Other tourist attractions also witnessed a rise in the number of international travellers. Starting at 20 million, the number of visitors to Southeast Asia gradually climbed to approximately 50 million. Both Sub-Saharan Africa and South America only had more or less 10 million tourists at the start of the period, and then reached 20 million and 15 million respectively. Overall, people seem to travel more and more. North America remains the most popular tourist attraction, while Central and Eastern Europe is rapidly catching up.
