Please let's stop the thread to consider what you just wrote.
"but it's all I have to work (with)" ?
If you do not have proper information, you can not do the work. Work? What type of work? You can actually end up doing harm.
That is another reason I write here. Governor Cox just blamed social media for the radicalization of people. It is very easy to pour opinions that have little foundation in the internet, then algorithms that pairs similar views create echo chambers that perpetuate false beliefs. How much have you read about it?
A serious forum, needs discipline, both to have accurate content and proper civil discussion that would elicit a good exchange and promote truth searching.
About random samples (survey data) to gather information. Opinion polls are gathered fast and often and are different from academic research geared to establish facts properly. For its nature, the type of questions you can ask in an opinion poll is limited. In an academic research you can test deep and sensitive issues.
I think the Pew Research center does not do opinion polls. It has good reputation for the seriousness of their work. Doing research to estimate how much people understand from the teachings is extremely expensive. I do not know about such study.
There are effective ways of gathering information on "soft" issues that are sensitive. Often it means organizing groups and a professional leads a conversation in an atmosphere in which participants feel safe to share. (most definitely would not stop a person on his wayt o church to ask a question about a deeper theological teaching like "do you think Mary is the Mother of God")
It takes training to understand why we need to do it that way and how to do it well. It needs on the job training in a good practice to become good at it.
We have make huge advance in the area of data analysis, it has come with increased training. There is no way around it, people need to have the skills and training to properly talk about it. If you are interested, I have some materials to share and references. The book "Think Again (The Power of Knowing what You Don't Know") is a good start. I got it from the public library.
There is a lot of conversations about Humanae Vitae. Hard data is simple: the average Catholic family has about 2.2 children (again, that comes from Pew Research Center landscape study
https://www.pewresearch.org/religion/2025/02/26/religion-fertility-and-child-rearing/) (it is in line with mainline Protestans and below evangelicals - 2.3)
Considering how unreliable natural birth control sanctioned by the encyclical letter is, we can suspect that most Catholics in the US use contraceptives not sanctioned by Humanae Vitae. The average is still lower in Europe, and possible higher in developing countries. The Vatican is most probably aware of it. In the least, they have data on baptisms and marriages in their parishes all over the world.
Studs Terkel talked with a lot of people, across socio-economic strata and geographical areas to write his books documenting oral history. It is a full time job, It probably took years of research - you need large samples if you want to say something relevant. His work inspired people that do serious research, especially in the area of "case studies". His journalism work is respected and has inspired data research.
Pople Leo XIV first formal interview may give light to the pressing issues for his papacy- wage inequality is at the top. Here I want to share a work on data analysis which echoes Studs Terkel history of the Depression.

Anne Case and Angus Deaton coined the term "Deaths of Despair"
The research of Deaton, for which he got a Nobel prize, took years of research, with good data. It is worth reading about it to get a sense of the effort it takes to be able to make such statements in an accurate proper way. Yet, when you get to it, the statement can be most effective- Pope Leo XIV is listening.
The severity of the issue is probably one that has kept the use of contraceptives out of the priority agenda in the Catholic Church (this is my subjective educated guess - an hypothesis to be tested). Families are struggling, and they do not want to go back to Dickensian times in which parents left children that they could not support in orphanages.
Returning to the thread, I quite agree that protestants do not often talk about Mary. I said it several times, in different contexts. Marian adoration is strictly Catholic. Protestants, although their core teaching calls Mary mother of God, are guarded about possible misinterpretations that would lead their flock to "Catholic superstition" (in the words of Calvin). If we are in agreement, why do you make an issue about it? Am I missing something?
