The graph shows information about the percentage of government spending on roads and transport in 4 countries in the years 1990, 1995, 2000, and 2005.
Overall, what stands out from the graph is that there were considerable upward trends in the income of both the UK and the USA, while Italy and Portugal have different changes. Another interesting point is Portugal, because over around 15 years there was a little change in spending on roads and transport, but the difference is small between Italy and Portugal. Portugal is a little bit higher than Italy, around 5%. The USA and the UK are very little compared with Italy and Portugal. The USA is a little bit higher than the UK, around 4%.
Looking at the details of the graph, Portugal in 1990 had 28% and Italy at that time had 20%. The difference between them was 8%, but after 5 years, in 1995, it changed to around 5%. Five years before it was 8%, and 5 years after it was a 5% difference in Italy. By the way, in 2000 they were all the same, but after 5 years everything changed. Italy and Portugal fell by 10% both and became 20% for Portugal and 14% for Italy.
By contrast, the USA and the UK had a little change, both of them. In 1990, the USA had a little more than the UK, around 2%. After 5 years, the UK became more than the USA, around 2%. But still, everything came back to the same place. The USA became much more than the UK, around 10% in 2000, and after 5 years, in 2005, there were almost no changes compared with 5 years ago
