This is just a selection of a handful of findings for 2019 (tables 27, 43, 130, 131, 132, 133, 134, 148, 150, 199, 201) and a longitudinal trend table for years 1991 through 2019 (these and many other tables are available in the folder named ‘all 2019 tables.’ Of course feel free to explore all of the results and review any of the tables, but for this project, please direct your attention to the tables numbered and mentioned above). Please identify three trends in numbers overtime or a noticeable pattern across different categories that grab you as intriguing, surprising, confirm your knowledge or challenge your expectations. For example, stating that in 1991, 51 percent of high school participants reported having had sex is NOT sufficient. But if you observe that from 1991 to 2013 the number of high school students who report having had sex drops from 51 percent to 46 percent — you have identified a trend! Similarly, it is NOT enough to simply document that 2.9 percent of females in 9th grade report having had sex before the age of 13. But if you state that 2.9 percent of 9th grade females report having had sex before the age of 13 compared to 8.7 percent of 9th grade males — you have found a noticeable pattern across categories.
After you have identified the three trends, please write them up, making sure that for each of them you
1. identify the table your data is coming from,
2. record exactly the numbers and the categories that factor into your findings, and
3. in your own words, explain what you observed. For each of your trends, your write up need not be longer than a page.
