The chart shows integration problems for people living abroad

Is my writing fluent? How can I improve my writing score in the Ielts test? Please, help me. Thank you so much.

The summary is about the chart which shows information about the problems people have when they go to live in other countries.

And this is my paper:

The bar chart provides information about the dilemma people face when they live abroad by diverse ages.

For the group of the middle age people in the chart, financial solutions which comprises 35 percent is a big deal. And the youngest group also has an approximate percentage of the older, it is 34 percent. While only 29 percent of people over 55 years old reckon that sorting out finances arduous.

The figures of people find sorting out healthcare is a significant problem in the middle age group and the oldest group are quite equal, which is 37 percent and 36 percent respectively. And the percentage of the youngest group is a little bit lower, at 32 percent.

By contrast, the people from 35 to 54 years old think that finding somewhere to study for their children is problematic, with 19 percent. However, the people over 55 years old has much lower percentage which is 2 percent, and the youngest group is 6 percent.

Overall, the data on an issue between ages is not much different, most notably that the percentage of middle-aged who think it is much more complex to find school for their kids than others.

Can i use:
( agonizing) dilemma instead of problem?
financial solutions instead of sorting out finances?
