An estimated 95% of all eggs in the United States are produced in conventional cage systems, sometimes called battery cages. [They] typically provide each laying hen an average of 67 square inches of floor space. In some egg operations, hens have less space.

It's hard to find quantitative data on your specific question. Even on vegetarianism and veganism in general, there are only very few quantitative and representative scientific studies.
Faunalytics published a Study of Current and Former Vegetarians and Vegans in 2014, indicating that people who were raised vegetarian might be less likely to abandon ...
The Census of Marine Life concluded in 2010 that 90 percent of the large fish are gone, primarily because of overfishing. This includes many of the fish we love to eat, like Atlantic salmon, tuna, halibut, swordfish, Atlantic cod. If we don’t allow for proper recovery, these fish risk total extinction.
Novogratz, A. and Velings, M. (2014). The ...
Luckily, Wikipedia has a page called Vegetarianism by country which has a table listing data for 38 countries.
Sorted by percentage:
India: 31% (375,000,000 people, 2014) [no surprise here]
Brazil: 14% (29,260,000 people, 2018)
Switzerland: 14% (1,176,156 people, 2017)
Taiwan: 14% (3,297,011 people, 2015–2017)
Israel: 13% (1,046,000 people, 2015)
As a disclaimer, I am not sure you can prove anything to someone who is close minded and it is self evident that animal slaughter rates are linked to consumption of animal products.
With that said, compile the international statistics.
Here is a list of approximate rates of Vegitarianism by Country
There are a few ways that genetics interacts with diet. The study of these interactions is called nutritional genomics. Nutritional genomics has two sub-disciplines, nutrigenomics (the study of diet's effect on gene expression) and nutrigenetics (the study of how genetics effect response to nutrients). A second relevant area of study is on genetics and ...
Getting the exact figures requires a lot of effort, so I am going to concentrate in getting the order of magnitude. Also, another factor that makes the effort grow considerably is the various types of meat that are being eaten: beef, pork, broilers, other Chicken, turkey, fish etc.
So, let's consider the beef. This article provides little insight about beef ...
Reliable figures over time are hard to come by. Different surveys are not comparable because they ask different questions; some collect figures for households and some do individual counts. The other problem is that polls use relatively small samples so an extra few people reporting that they are vegan or vegetarian will skew the figures considerably. A ...
The vegetarian society has some statistics about the UK percentage of vegetarians.
Their most recent figures come from Department of Health and Food Standards Agency (FSA) - National Diet and Nutrition Survey which records that vegetarians seem to consist of around 2% of the UK population.
Statistics for countries is patchy, especially as the few surveys ...
Explanation: People are born vegetarian here, I have myself never eaten meat or egg for that matter, cow or buffalo milk is fine. I believe this is tied to Hinduism which is the prominent religion in India. To start not being a vegetarian can be more challenging than being vegetarian. But slowly younger generations seem to be breaking this trend to ...
I think it's India. I, myself, am a vegetarian by birth. 78% of the population of India follow Hinduism. And some of the sects in Hinduism require people of the sects to be vegetarian. According to statistics, 33% of Hindus in India follow vegetarianism.
Religions like Buddhism and Jainism, which were born in India, guide people who follow that religion to ...
Since it seams your concern is really about having vegetarian options in restaurants rather than about pure demographic data, here are two resources that I use when traveling:
Happy Cow is basically yelp for vegetarian and vegans.
Vegan Food Is Everywhere is an interactive map of vegan food offerings.
But if you do want the demographic data, Wikipedia ...
I believe there is currently no reliable dataset that would include the kind of information you are asking about. Although for vegetarianism (with veganism included) there is some data, for veganism it is only for a couple of countries and even for these, the sources are somewhat dubious (like for Israel, where these are estimated by a television poll).
Assuming you mean >50% of the population in an area by majority, the answer is no, there are no countries where this is true.
According to Wikipedia, the country with the highest amount of vegetarians is India, with a (rather staggering) 29%–40% of vegetarians. That's approximately 361 million people, which is hard to visualise, I'd say.
This article ...
Israel is becoming well known for it's very rapid rise in citizens choosing a vegan diet.
Numerous articles (see this and this) attempt to explain the reasons behind the rise:
As for your second question, it is tough to say what the best strategy might be. Although, for many people a religious conviction can certainly send them down this path. In general, ...
It is extremely hard to find exact info on vegetarianism figures. However, meat consumption might give us a rough idea. I'm using NationMaster to find these figures. From countries with highest consumption of beef and veal to lowest:
# Country KG of Meat
1 - Argentina - 40.12kg
2 - Paraguay ...
A 2004 study of 75 vegan women in Germany showed that iron deficiency was substantially more common among vegan young women (40%) than the baseline for adolescent girls and women (11%) in the United States. However, only 4% (n=3) had iron deficiency anemia which is about the same as baseline.
A 2015 study of 60 young women in India (30 vegetarians) showed ...
The hypothetical village story does not convince.
I'd argue that the meat supplier simply finds himself with 20 chickens he can sell to another village.
Because he needs to sell the chickens the price may fall and this can cause other people to eat more chicken.
No, not convincing enough.
I think it's the wrong approach to try to prove the challenge.
On a simple example:
There is a village with 100 families. All families eat meat so the daily need is 100 kg of chicken.
Let 1 chicken equal 1kg of meat.
Day 1 - 1 family stops eating meat.
Day 2 - The daily need of the village is now 99kg.
Day 3 - Another family stops the meat.
After 30 days, 20 families stopped consuming the meat.
Now the daily ...
