"The chart below shows some of the problems people have when they integrate into the new countries and the varsity of each difficulty according to age.

The biggest problem for the people aged 35 to 54 group is sorting out healthcare, experienced by 37 percent of them. It's a little bit higher than the oldest group (36%) while the percentage of the youngest one who have this trouble is 33%.
The middle age also seems to have the most problems related to money, at 35% compare with 34% of 18- to 34-years-olds and only 28% of the oldest group experience this.
The last problem - finding schools for their children- is still found the most difficulty by the middle age, accounting for 18% of them while the youngest people find this easier and even fewer over 55 people undergo the problem.
In general, all age groups experience the same difficulties but the middle age seems to deal with the most problem."
