Top-coding of net income
80%
Description
Hi, how would I find out if observations of the following variables have been top-coded?:
fimnnet_dv
fimnmisc_dv
fimnprben_dv
fimninvnet_dv
fimnpen_dv
fimnsben_dv
I have read the documentation but can't seem to find information specifically on the top-coding of these variables.

Sorry for the delay in getting back to you.
Based on the user guide description of topcoding, all these variables are top-coded but we are still waiting to hear back from the Income Team for confirmation.
Best wishes,

Thank you. Could you please ask the Income Team how I can identify which individual observations have been top-coded?

Hello Leah,
Currently the only way to identify the cases where income has been topcoded is using the _tc variables. This will tell you whether the corresponding income variable's components were top-coded. And to know whether the specific component was topcoded please check the topcded limit described here. If the value is less than this then it was not.
If you wan to access the non-topcoded income values please apply for the Special License version of the data:

As fimnnet_tc doesn't exist, how would I know if fimnnet_dv observations are top-coded? fimnnet_dv is comprised of 6 components, and only one of these components (fimnlabnet_dv) has a top-coding dummy variable. How can I use the components to work this out if only one of six components has a top-coding indicator - can I assume that if a component has no _tc variable, the component is not top-coded?
Thank you.
