12-month change: Prices increase in all eight major components

On a year-over-year basis, prices increased in all major components of the CPI in March. Except for alcoholic beverages and tobacco products, prices rose at a faster rate in March than in February.

The largest increase occurred in the transportation component, where prices rose 6.6% in the 12 months to March, after advancing 5.1% in February.

In addition to higher gasoline prices, consumers paid more for passenger vehicle insurance premiums and for air transportation. Prices for the purchase of passenger vehicles rose 0.2% in the 12 months to March, following a 0.9% decrease in February.

Food prices rose 3.3% in the 12 months to March, following a 2.1% rise in February. Prices for fresh vegetables rose 18.6%, as bad weather in Mexico and the southern United States reduced supply. The cost of meat rose 5.0% in March, as beef and pork prices increased. Higher prices were also recorded for bakery and cereal products as well as for dairy products.

Shelter costs rose 2.4% in March, after increasing 2.2% in February. In addition to higher prices for fuel oil and other fuels, as well as for electricity, homeowners' replacement cost increased 3.2% in the 12 months to March.

The recreation, education and reading price index increased 2.3% in the 12 months to March, after decreasing 0.3% in February. The difference can be mainly explained by traveller accommodation prices, which increased 1.7% in March compared with the same month last year, after posting a 10.7% decline in February. The price decline in February was more the result of higher prices for hotel rooms in February 2010 during the Winter Olympics in Vancouver rather than recent price decreases.
