Writing Task 1: happiness scale in married and unmarried couples

The first bar chart reveals information of survey outcome on happiness scale, categorized by married and unmarried couples, located in the US, classified by four different age group group while the second one shows the happiness ratings of children existence on married people. Overall, it can obviously be seen that married people aged 18-29 has the highest percentage of happiness and children at the age under 18 brings the greatest happiness on married couple.

With regard to the first chart, young married people on the 18-19 age group overtake the largest proportion of happiness, standing at 45% followed by the age group of 30-49 and 65 and over which have the same point at 44%, 1% less than that of younger. Next, married couples who are 50-64 take the least percentage of happiness. Turning to unmarried people, people who are 65 and over 65 years old are the happiest group., showing more than a third of proportion while the age group of 50-64 and 18-29 become the unhappiest people owning ratio at around a fifth.

Equally important, having children at the age more than 18 brings the lowest scale of happiness, staying at 41%, which comes after owning no children and having children under 18 years old classification, at 43% and 44%, respectively. It means that married people who have children aged less than 18 have the biggest happiness.

This is a very difficult type of essay to write. You have a lot of errors, but even a native English speaker would make some errors when trying to write about a chart like this one. Below, I'll make a few corrections:

... shows the happiness ratings from the children existence of married people.

Overall, it can obviously be seen that married people aged 18-29 has have ...

With regard to the first chart, young married people on in the 18-19 age group ...

....which comes after owning having no children and having children under 18 years old classification , at 43% and 44%, respectively.

For this last sentence, I have a suggestion to improve the style:

It means that married......the biggest happiness. One insight to be gained from this chart is that married people who have children under the age of 18 report experiencing the most happiness.
