Hello ACS Data Community,
I recently stumbled upon a perplexing issue in the 2022 ACS 5-year estimates that I believe warrants discussion. According to the official enrollment statistics provided by BYU-Idaho (byui.edu/executive-strategy-and-planning/institutional-data/official-enrollment-statistics), the ratio of male to female students is roughly balanced, hovering around a 1:1 ratio.

However, this seems to be in stark contrast with the ACS 2022 5-year estimates for the Rexburg, ID Micro Area, specifically in the S12002 table.
https://data.census.gov/table/ACSDT5Y2022.B12002?q=B12002:%20Sex%20by%20Marital%20Status%20by%20Age%20for%20the%20Population%2015%20Years%20and%20Over&g=310XX00US39940
The ACS data indicates a surplus of 5643 never married women in the area, which seems implausible given the university's gender ratio. This discrepancy raises serious concerns about the accuracy of the ACS estimates. Could this be a methodological error or a misinterpretation of the data?
I reached out to the ACS team regarding this issue, but they firmly denied any error in their data. This response is a bit disconcerting as it challenges our understanding of the demographic dynamics in university-centric areas like Rexburg. I'm curious to hear your thoughts and experiences regarding similar discrepancies in ACS data, especially in areas with significant young adult populations.
How do we reconcile such stark differences in data from reliable sources? Are there any methodological nuances of the ACS estimates that might explain this discrepancy? I look forward to a vibrant discussion on this issue.
On the one hand, your experience shouldn't count for nothing, you're on the ground and that gives you insight that can't be gained through a survey. On the other hand, you only know what you know, and…
Aefcmj, I need to further affirm your suspicions. The discrepancy seems to be centered around the BYUI campus, which in the 2018-2021 data was 5% male.Even stranger, looking at the 2013-2017 data, it was…
I pulled up the College enrollment in the Rexberg Micropolitan area and I include it here. It does show the typical gap between men and women enrolled.
From a quick look at data on the area, there was…
Interesting. The Rexburg, ID Micropolitan Area seems to be all of Fremont and Madison counties (https://www2.census.gov/programs-surveys/economic-census/2007/reference-maps/id/metro/2007-us39940m-rexburg-id-micropolitan-statistical-area.pdf), so I'm guessing that there are other residents there who are not part of the university.
It might also be worth looking at some of the school enrollment tables (any that start with B14), for example, B14002 actually lists people enrolled in college undergraduate years by sex. One thing to note though is that ACS only captures yes/no on school enrollment, not on any particular institution. So this would also include people who are enrolled in any other institutions who live in the micropolitan area (community colleges, other universities, and could even be online programs).
Right, BYUI's report supports this. Note the higher counts of women enrolled online
Online data make no sense, because online school can have no building but just a website and be registered in some city.
That makes no difference to the ACS. You seem to take issue with the ACS reporting more women than men because it's inconsistent with BYUI enrollment counts. But the ACS is not counting enrollment, either online or in person.
This is all based on my personal experience, I observed that when I lived in Rexburg, there were more men than women, so there were some men who couldn't find wives
On the one hand, your experience shouldn't count for nothing, you're on the ground and that gives you insight that can't be gained through a survey. On the other hand, you only know what you know, and unlike you, the ACS data is based on a random sample, which reaches people likely outside of your orbit.But there's a third hand- The difference between the male and female populations is most stark at 18 and 19 years old, never married. 2,481 male, 8,510 female. That is a very large difference, much larger than for any other age group. That's weird!
Aefcmj, I need to further affirm your suspicions. The discrepancy seems to be centered around the BYUI campus, which in the 2018-2021 data was 5% male.Even stranger, looking at the 2013-2017 data, it was much more balanced, at 44% maleAccording to the data, the male population dropped from 541 to 80 over the course of these 5ish years. Of course, I'm looking at block groups and weird things happen in block groups, but clearly it's affecting the data for the whole area.
Male vs. female residence halls?
From a quick look at data on the area, there was a second College in the area that went out of business in 2021, and it may have been partially included in the data since it is 5 year study. Most generally in College's today one has a large gap between Women and Men, with men not being as likely to enroll or graduate. BYUI may be different in some ways, since they also have a count of "Returning Missionaries" on their website.
I would suggest looking up the data in IPDEDS of colleges in the two counties, and seeing if there was enrollment before. The College that closed, closed in 2021 so that may have skewed the data more male. IPEDS is put out by the NCES, and reports what colleges report to it.
I do not think that a marriage gap between women and men is enough to explain this. There is a general gap in many places, because just the presence of a surplus of men or women would not account for such a gap on its own. Put simply women no longer need to settle to support themselves, and may not want to marry someone less accomplished than they are.

No. This is suitable for describing female academics in Boston college town or female professionals in Manhattan NYC, but it is definitely not suitable for a place like Rexburg where everyone wants to get married.
