creating a variable that assigns the same value for each id

[Sujin Shin]

Hello, I am working with a panel data that has household id (h_id) , individual id (h_pid), age, relationship with the householder and etc. I have attached a screenshot of a part of the dataset.

I want to specify whether an individual is a child (i have set the age from 0~10) or not.

So far, I have created a dummy variable to identify the observations with the age 0 or 1 (because some are born in between the survey dates).

What i want to have is a dummy variable, child1, that assigns 1 to each individual id if he/she is a child. Something like below

h_id h_pid year age child child1
693 69352 2015 1 1 1
693 69352 2016 2 0 1
693 69352 2017 3 0 1
693 69352 2018 4 0 1
693 69352 2019 5 0 1

Please help me to code this. Thank you.

g child = inrange(age,0,10)

Edit: In the future, please do not upload screenshots or manually post data, when showing problems with data, always use the dataex command.

bysort h_id: egen child1 = max(child)
