Hi Datameet,
I had a question about the Indian TUS 2019.
The 2019 data has indicator variables to understand whether multiple and simultaneous activities were conducted in a particular time slot. I noticed that in a given time slot where multiple activities were conducted, there is only information about the major activity, with values being missing for the other activities (as you can see in the screenshots below).

This is how I am interpreting the missing values:
- If multiple activity = Yes for an activity, all subsequent activities in the time slot are considered to be multiple activities
- If simultaneous activity = Yes, all subsequent activities in the time slot were performed simultaneously with it
- If simultaneous activity = No, none of the subsequent activities in the time slot were performed simultaneously
This means that it is not possible for some activities conducted in a particular time slot to be simultaneous while some are not.
I wanted to confirm whether our understanding is correct since I have not come across any documentation regarding this.
Best,
