The line graph provides information about the shifting movement of taxation and the amount of credit available in the UK while the bar chart compares the expenditure on three different merchandise types, both from 1990 to 2010. From an overall perspective, it can be observed that the rate of taxation is inversely proportional to the availability of credit and the levels of consumer spending.
To begin with, the two figures show that there is a positive correlation between the amount of credit available and the spending of UK customers. The availability of credit rose considerably to 30% in 1995 and peaked at 60% in 2005 before fell sharply after 2010. Spending on the three categories (food, household appliances and clothing) showed a similar pattern that all of them reached the second-highest point in 1995, then peaked (at 3, 5, and 5. 5 respectively) in 2005.
On the other hand, the figure of taxation seems to correlate negatively with levels of consumer spending. There were significant drops in taxation in two 5-year-period, from 1990 to 1995 and from 2000 to 2005, while at those same time, consumer expenditure in the UK increased rapidly.
Seen together, the more credit is available, the more consumers spend, whereas when the rate of taxation increased, consumer spending decreased.
