-## Warning about `tmd_2021.csv` file
-
-There is a special-purpose `tmd_2021.csv` file that includes 2021
-Tax-Calculator output variables and the pre-optimization weight,
-`s006_original`.  The weights and input variables in this file are not
-rounded for Tax-Calculator input (as they are in the `tmd.csv` file),
-and therefore, there has always been minor differences between the
-content of `tmd_2021.csv` and `tmd.csv` files.  As a result, using the
-`tmd_2021.csv` file is not recommended.  There are plans to remove the
-`tmd_2021.csv` file in the future.
