1. Create a copy of this spreadsheet. Births-in-united-states.xlsx
2. Data about your birth date.
   1. When were you born?
   2. What day of the week was it?
   3. How many people were born in the US on your day.
3. One paragraph describing the social and economic conditions of the year you were born. (See links below.)
4. Use the dataset to generate a pivot table with related data and a graph of your choice connected to that new pivot table.
5. Provide analysis of the data, answering the following questions. (Can you use the pivot chart as evidence to support your answers?)
   1. Why are there two or more bands in the scatterplot? 
   2. Why does the data ‘make waves’, display periodic crests and troughs?
   3. Notice the peak in the data on 9/5/2007. Why have births in the US been declining since then?
6. Please cite your sources. (Students may get help from friends. However, please submit your own work and your own personalized analysis.)
