The given line graph illustrates the proportion of Infractions in three different categories in a particular city of the United States from 1980 to 2000.
Overall, there was an increase in the total amount of crimes, which was the result of levelling up in house burglary and street robbery. In addition, car theft saw a decline, surpassing the car theft to become the most serious crimes.

Opposite changes, but to a less or extent, can be seen in the figure of house burglary, rising from approximately 200 to reach a peak of 315 in 1990, then fall about 100 units in the next five years and continue to grow to just over 250.
About 50 of street robbery crime cases in the beginning of the period, with subsequent rising 100 in 1990, then return to slightly higher the initial value in 2000.
