Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits, it appears that you have added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. You can have a look at the tutorial on citing sources. Thank you. OhNoitsJamie ^Talk 13:26, 14 March 2024 (UTC)

It is not "original research" - the figures for the 1950 and 2010 census are in a graph in the article. I have not made up the the demographic collapse of the city - it is right there. 2A02:C7C:E183:AC00:E98C:C888:65C4:8C49 (talk) 13:29, 14 March 2024 (UTC)

Please do not add original research or novel syntheses of published material to articles as you apparently did to Pittsburgh. Please cite a reliable source for all of your contributions. See WP:SYNTH. While your statement is arguably correct, you are coming to a conclusion through the comparison of two sources. "Do not combine material from multiple sources to reach or imply a conclusion not explicitly stated by any source." To say this, add a citation directly following your contribution. Further, to include the phrase "population collapse" you will need to have a source both specifically defining pop. collapse and applying that definition directly to Pittsburgh. By the way, thanks for your editing on Wikipedia, just be careful!
