Canada and China

1)

Life expectancy at birth Canada : male: 78.81 years                                           

                                                   female: 84.1 years

Life expectancy at birth china : male: 72.68 years                      
                                           female: 76.94 years


i was surprised that Canada has has a better life  expectancy  maybe Canada has better Heath care . maybe the heath care it not good or because china has so many people living there.   

2)       Literacy Canada:  male: 99%

                                      female: 99%

                                      total population: 99%

            Literacy china  : male: 95.7%\

                                    female: 87.6%

                                    total population: 91.6%    maybe china has a lower literacy  rate  because they have more people .  more people , more people not going to school .why does china have a lower literacy  rate if they go to school for a really lone time

  Population Canada : 34,030,589

      Population china :  1,336,718,015          chine 1302687426 more people then canaden . why is there more people
