+# Total Private Construction Spending
+
+This dataset is retrieved from the US Census and concerns the total private 
+construction spending. Potential change points occur at recessions. The data 
+is obtained [from this Census 
+page](https://www.census.gov/construction/c30/historical_data.html) using the 
+"Private" series from the "Not Seasonally Adjusted" column in the "Monthly" 
+table. Alternatively, use [this direct 
+URL](https://www.census.gov/construction/c30/xls/privtime.xls).
+
+According to [this
