According to the first chart, 45% of married couple in the youngest group are happy, compare to 21% of unmarried people with the same age. The happiness levels of married people aged 30-49 and 50-64 are 44 percent and 40 percent respectively, which two times as great as the figure for people who are not married in the same age group, which only 22% and 21% respectively. It is noticeable that, the happiness ratings for US people in their 65 or more are the highest rate for unmarried people at 34%, compared with that of married couple at 44%.

            Moreover, married couple who have children under 18 are the happiest among three groups with the percentage of 44. Follow by people who don’t have their offspring and people with 18 plus year-old children at 43% and 41% respectively.

 In general, it can be seen that married couples are likely to be more satisfied with their life, as opposed to unmarried people. Children also have a significant influence on the statistics.

 According the data of the first chart, celibates have low level of happiness compared to wedded people. While the highest score of affianced people is 45% for people in 18-29, the lowest one is 40% for people in 50-64. The score of persons at 30-49 is the same as ones above 65 with 44%. Besides, the percentage of the first three age groups of unwed people fluctuate from 21% to 22%. But then the data rises dramatically to 34% for individuals above the age of 65. 

Moving on to the second chart, it demonstrates how children have an impact on the ratings provided by engaged couples. The humans who have children under 18 have the largest ratings of happiness with 44%. However, this data goes down to 41% when children grow up. Couples with no children also have a high score of happiness with 43%.

In conclusion, the two graphs show the significant difference in happiness levels between persons who have and do not have a spouse. There is a tiny variation in how children under the age of 18 impact their family's happiness, but it does not demonstrate a major decline whether they have children or not. 

 

Overall, it can be clearly seen that married people, whether they have children or not, are happier than unmarried groups.  

According to the data from the first chart, the figures for married people with four types of years are higher than single groups. The 18-29 group has the highest enjoyment level, namely 45%; while the 50-64 group is the lowest, about 40%. The others, 30-49 group and over 65 group, have the same percentage which is 44%. In comparison, the first three groups of singles have the lowest percentages, just between 21% and 22%. Unlike three groups mentioned above, over 65 unmarried people seem to experience significant difference and their enjoyment level is 34%. 

Futhermore, married couples who have children under 18 years old are happier than the other two groups that have only and 18-year-old children or do not have any child. The enjoyment percentages of married couples have under 18 years youth is 44%, while those who doesn’t have a youngster  and have 18 year and only a child are 43% and 41% respectively. 

Taking a look at the first chart, it is clear that single people have relatively low level of happiness compared to married ones. For engaged people, the scores do not differ much across the four age groups. The highest score is 45% for people in 18-29, and the lowest one is 40% for couples at 50-64. People at 30-49 and above 65 offer the same rate of 44%. When it comes to single people, the first three age groups only show about 21% in satisfaction, which is only a half of the lowest rate given by engaged people approximately. But then the data rises  dramatically to 34% for everyone aged above 65. 

Moving on to the second chart, it shows how children affect the ratings given by engaged couples. People who have children under 18 have a tendency to feel most happy, with 44% in ratings of happiness. However this gradually falls when children grow up. People with no children also have a pretty similar level of happiness compared to couples with children under the age of 18, with only 1% in difference. 

In conclusion, the two graphs have compared the impressive difference in level of happiness between people who have a spouse and those who do not. There is a slight difference between how children under 18 and above 18 affect their family happiness, but whether they have children or not it does not show significant decrease.
