What is happening in this graph? | Weddings

The article asks if we are experiencing a marriage boom or a marriage boom. “Marriage rates have been falling for decades and hit a record low of 6.1 per 1,000 people in 2019, down from 8.2 in 2000. The decline has been accompanied by a decline in fertility, which has also reached a new low before the outbreak of the coronavirus. .” Will all these marriages result in a baby boomlet?

Here are some of the student titles that capture the stories of these graphics: “Something Borrowed, Something Blue, A Predicted Surge In Weddings Is New” by Maggie of Saint Elizabeth’s Academy in Morristown, NJ; “Covid Ruined Weddings” by Ms. Mitchell’s Grade 5 class in Mississauga, Ontario; “Will weddings be operational after Covid?” by Evangeline of Concord, NH; “The Great Wedding Business Depression” by Cynthia of Penn.; and “2020: The Year Weddings Paused” by Gabriella, “Is Love Dead or is Covid Alive?” by Paige, both of Gilbert, Arizona.

You might want to think about these additional questions:

  • The last time there was a jump in the number of marriages was in the 1980s and it was not as large as expected for 2022-2025. Why do you think there was an increase in the 1980s? When will you project that the 1980s marriage bump might have an “echo” bump (a bump related to the previous bump) in marriages? Explain your answer.

  • Some think the economy will change because the pandemic could change the way young people think about getting married, having children and buying a house. Some of the factors that may affect how they think about marriage, children, and property include working and schooling remotely during the pandemic, government checks, and cutting expenses while observing social distancing. It could have a major effect on different parts of the economy, including everything from wedding dresses, child care and furniture. What do you think?

Below we define mathematical and statistical terms and their relationship to this graph. To see archives of all Stat Nuggets with links to their charts, head over to this index.


A time series stepper graph, sometimes called a staircase or piecewise graph, has a value on the y-axis over an interval of time on the x-axis, “stepping” from one time interval to the next interval. It is used when the data relates to a period of time, such as a week, a year or a decade.

In the Marriage chart, the horizontal “steps” last for one year (data is collected every year) and the vertical “jumps” represent the change in the number of marriages from the previous year.

The graph of “What’s happening in this graph?” is selected in partnership with Sharon Hessney. Ms. Hessney wrote the “revelation” and Stat Nuggets with Roxy Peck, professor emeritus, California Polytechnic State University San Luis Obispo, and moderates online with Kristina Barnaby, middle school math teacher at Fairfield Country Day School in Connecticut.
