APA in-text citations for long author lists and government data (retrieval dates)

[Aubrey69]

I'm a graduate student in psychology, and I'm finalizing my thesis literature review. While I'm generally comfortable with APA style citations, I'm struggling with a few specific formatting issues. How do you correctly cite a source with multiple authors in-text when there are more than twenty authors? Also, what is the proper format for citing a dataset retrieved from a government website, and do you include the retrieval date if the dataset is static? My university's style guide isn't clear on these edge cases, and I want to make sure my references are flawless before submission.

APA 7th in-text citations for works with many authors: you always use et al. starting with the first citation, for three or more authors. So you would write (Ng et al., 2023) rather than listing all authors, even if there are 20+. If you cite more than one work by the same author in the same year, add a, b, etc. (Ng et al., 2023a; Ng et al., 2023b).
