The given graph presents the amount of satisfaction level of medical care in four different countries in three distinct years: 1991, 1998, and 2007. Units can be measured in percent.
Overall, all four countries were steady except for Canada, which experienced clear vibration in the numbers. It is clear that the gap between these countries narrowed over a period.
According to what is depicted, in 1991, in Canada, close to 60% of people were satisfied by the medical services. However, the level dramatically declined to 20% in 1998. Following this decline, this level doubled in 2007. Additionally, there were not clear changes in the UK; the healthcare services stood the same for the three years.
In 1991, the Netherlands experienced an increase of about 2% marginally over a three-year period. Furthermore, in the US, in all three years were identical levels with equally 10%. The US was the lowest country in that duration.
