Partition Of India To India/pakistan In 1947

[Bharatvarsh]

I have a question regarding partition, I have read in some articles that Lahore was Hindu majority but was given away by Congress, when they say Lahore was Hindu majority do they mean the city of Lahore or the district of Lahore (if there was such a district), can someone enlighten me on this point, thanks. By the way the following is one article where I read this:

"like why Hindu-majority areas like Lahore, Sylhet and Chittagong were given away to Pakistan by Nehru [63]."

Also does anyone here have the religious demographic statistics of Lahore before partition.
