For what it's worth, we now have a political survey of sorts conducted by YouGov.
Or rather, we have two.
https://ygo-assets-websites-editorial-emea.yougov.net/documents/Internal_Zoos_250327.pdf
This survey in particular looks at different types of animal-groups and surveys people as to how acceptable they are to keep in zoos. The people are classed on the following categories; the party they voted for in the 2024 general election [Conservative, Labour, Lib-Dem, Reform], the option they voted for in the 2016 Brexit referendum [Remain, Leave], their gender [Male, Female], their age [18-24, 25-49, 50-64, 65+] their social grade [this refers to their rank on the 'economic ladder', ABC1, C2DE], their resident constituent country [England, Wales, Scotland], and region of England [North, Midlands, London, Rest of South].
The animal-groups used in the survey were as follows; Great Apes, Big Cats, Elephants, Giraffes, Bats, Small Primates, Meerkats, Crocodiles, Snakes, Zebras, Penguins, Parrots, Lizards, Insects, Wolves, Goats, Bears, and Frogs. A bit of a strange selection, as you could make the points that these animals do not make up most of any given zoo's collection, but it is what it is. As far as goes political parties, I did observe often that the left-leaning parties [Labour, Lib-Dems] were more skeptical or negative than were the right-leaning parties [Conservatives, Reform] who were generally skewed more positive. That is to say that the skew present was not a very obvious one, and there were some instances where the trend was bucked, and a right-leaning party was more disapproving of one thing or another than a left-leaning one.
And so to look at everything as it was cumulatively; of the eighteen groups of animals inquired about, only five seemed to show a decisive 'unacceptable' ranking - big cats, elephants, great apes, bears and wolves. Which is perhaps to be expected as these animals, which are usually large in size, have historically been the ones that anti-zoo groups were most attracted to, and chances are in the context of the word 'zoo' the idea is one of a rather closed in environment [although London is the only surviving inner city zoo in the UK] ... where of course the public is somewhat aware of the different ideas about large animals in captivity. Three of the groups - giraffes [-], zebras [+], and crocodiles [+] were more indecisive - in the case of these animals, the acceptable or unacceptable margin was only defined by up to three points - and in the case of giraffes, it was a 45:46 ratio as to acceptable vs unacceptable. As for the ten other groups, there is a decisive 'acceptable' ranking - so, if this study is to be believed, the public has rather little problem of the keeping of most smaller animals. And I do think it's more that the public is more wary about an animal's size than its cognitive abilities - as parrots are very intelligent but they get 61:32 for acceptable and unacceptable.
And the age also seems to all-but prove my hypothesis about older people being more critical towards the keeping of large animals than younger people ... looking at total acceptable and total unacceptable for the youngest age demographic, big cats in fact have an overall acceptable ranking although it's what I'd call indecisive - in the same way this age group has an indecisive unacceptable ranking for elephants and great apes - and if we look at 25-49, which you could make the point is the age group most likely to visit a zoo with children, elephants are the only group with an unacceptable ranking - and a very indecisive one [by 1 point!] at that! And even with the decisive negative rankings by the 18-24 group for bears and wolves, we do see that the 'unacceptable' percentages for all groups, and the more decisive unacceptable rankings, are within the two oldest age categories!
And so we look at the second poll:
https://ygo-assets-websites-editorial-emea.yougov.net/documents/Internal_Zoos_250310.pdf
This poll is more about questions about zoos; namely the following:
"How often, if at all, would you say that you visit zoos or wildlife sanctuaries?"; "When visiting a zoo, which animals do you most look forward to seeing? Please name up to three."; "Overall, do you think that zoos play a positive or negative role in the following? [animal welfare; animal conservation; human understanding of animals; relationship between humans and animals]"; "Would you support or oppose each of the following? [Phasing out the keeping of large animals in captivity; Banning zoos entirely]" All of the qualifiers are the same... but this time the Green Party has its own category. And so we have three left-leaning parties to work with.
For the first question... politically it does look like those of left-leaning parties are more likely to visit zoos regularly than are those of right-leaning ones... but the percentages are close so I don't think it's much of a decisive thing. And age wise it does seem like the two younger age groups visit zoos more frequently than do the two older ones.
With the second question it seems constructed better than the animal related question of the first poll... because it asks the one being interviewed as to what they particularly like to see. And as far as I can see there isn't really a political bias here. If anything two of the left-leaning parties seem more inclined towards elephants than the two right-leaning ones. Age wise there are animals that seem to be 'overall favourites' - elephants ranking consistently high, though somehow amongst the 25-49 group giraffes and lions rank higher in popularity than elephants. Whilst giraffes aren't too popular with younger people. Capybara does seem to have a dominating presence in the youngest category however - where in three of the categories it scores 1% or less in the youngest category it scores 4%.
And now for the proper questionaire... the question about animal welfare, overall, got 60% positive responses - that zoos play a positive role. Age wise... our idea that older people seem to be against zoos more seems a bit questionable... the 3 older age groups have a clear majority that zoos are good for animal welfare - whereas for the younger age group there is a majority but an indecisive one - 31:29 - and even more 13% of respondents in this age group responded with 'don't know', and 26% - not as much as 29 or 31 but not small enough to be snubbed either - responded that they have neither a positive or negative effect. Politically there seems to be a majority positive also, though again with left leaning parties typically having lower score than right-leaning ones - though Green seems a bit indecisive - with 50% positive, 25% negative, and 20% neither.
And now for the conservation of animals... 78% positive overall, 5% negative, and 12% Neither. Politically again right-leaning more positive but all parties fall in about the same range. And age wise the trend seems to be that older groups have more favourable view in regards to this. The 'understanding of animals' question has 76% positive... with all of the political parties being about on the same page, and this time there's a slight skew towards the younger groups with regards to positive responses. And the last response in this questionnaire... the one two do with 'the relationship between humans and animals'.... 64% positive responses, political parties are mostly in the same region as each other except for Green which is rather more skeptical... and age wise it is seen as more positive by older groups.
And so now we have the last two questions... the one about 'phasing out the keeping of large animals in captivity' seems to have a narrow margin of majority support with 51%... with the left leaning parties more supportive of this than the right leaning ones. The youngest age group seems most in support of this, with 56%... and the older age groups are a bit less decisive with values closer to 50%. And so we get to the last question... that of "Banning zoos entirely". And this was probably the one with the strongest opposition - only 22% supported it and 69% opposed it. The trend of left more negatively [that is, against zoos] skewed, right more positively skewed, Green even more negatively skewed can be seen again - But even then there is not strong support for banning zoos entirely politically anyways - and in addition to having the highest support for banning zoos, Green Party also had the highest ranking in the 'don't know' category, And even then had a majority [57%] of opposition. Age-wise, strangely, 18-24 and 50-64 seem quite close to each other; though as ever 25-49 seems most opposed to such a thing as expected... but so is 65+, although they outperform the 25-49 category twice - both in regards to their support of banning zoos entirely, and again for their opposition to this. Geographically there is a bit more clarity, with London having a clear majority of those in favour. But... however you splice it... the majority is fine with zoos existing.
I think it's a very 'take what you will' study... where one implies that older people are more against large animals in captivity but the other implies that younger people are more against it... who knows why. But if anything is constant between these papers, the 25-49 category, which seems the most likely to visit zoos with some regularity, does seem the most in favour of their operation and existence.
