Based on my observation of my Indian peers in the US (those about my age with young children and came to the US in 1990s-2000s), their children (born and being raised in the US) are usually much taller than the parents. I do not see the same pattern among Pakistani Americans.
Admittedly this is just anecdotal data, so I would appreciate if someone could point out any paper on the topic.
While searching for information, I did find that Indian height grew less than 0.5in from the generation who were adults in 1980 to those who were born in 1980 (PDF link to paper). However, I am looking at a later generational difference: Children born in the last decade compared with their parents.
A Nature paper shows how short Indian teens were in the 1990s.
