Click here for some seeds I have found while making this!
I am manually generating (via Amidst 1.13), thousands and thousands of default random worlds, while counting in an Excel file the amount of times each biome appears at the exact center (0, 0) of the map. The end. That's the project. This doesn't necessarily measures how likely is to find a certain biome, as it depends on various other factors (for example, you will never find Desert Hills in the middle of a tundra), but does the % of the Overworld each biome covers, and that is a faithful indicator.
Without further delay, here are the results.
Biomes are sorted by overworld coverage, in decreasing order.
Currently generated worlds: 12000
How to read:
{NumberID}. {Biome Name} - {# of worlds}({world coverage}%) (1.12 name, if different)
158. Snowy Taiga Mountains - 4(0.03%) (Cold Taiga M)
166. Modified Wooded Badlands Plateau - 4(0.03%) (Mesa Plateau F M)
167. Modified Badlands Plateau - 2(0.02%) (Mesa Plateau M)
8. Nether - 0(0%) (Hell)
9. The End - 0(0%)
20. Mountain Edge - 0 (0%) (Extreme Hills Edge)
40. Small End Islands - 0(0%)
41. End Midlands - 0(0%)
42. End Highlands - 0(0%)
43. End Barrens - 0(0%)
47. Deep Warm Ocean - 0(0%)

By temperature
Frozen oceans - 134
Cold oceans - 599

Semi-aquatic biomes (rivers and beaches) - 949 (7.91%)
Land biomes - 8124 (67.7%)

Desert - 700
Mountains - 1193
Forest - 1689
Taiga - 667
Swamp - 534
Snowy Tundra - 212
Mushroom Fields - 6 (excluding the shore, as it is both a beach and a river and therefore a semi-aquatic)
Jungle - 252
Birch Forest - 522
Dark Forest - 370
Snowy Taiga - 61
Giant Tree Taiga - 161
Savanna - 470
Badlands - 119
By 'role' (aka whether the biome is a main biome, Hills, Mutated etc)
Main - 5988
Hills - 1678 (including Savanna Plateau and Wooded Mountains, as they generate as other Hills)
Edge - 29 (only Jungle Edge)
Mutated - 353
Mutated Hills - 76 (biomes that are both Hills and Mutated)
Mutated Edge - 0 (only Modified Jungle Edge)
WARNING: 12000 worlds is still not a big enough sample. This is quite imprecise and is still almost unable to stablish any rank of biome rarities, specially of the rarer ones. However, this is slowly becoming better over time, but is the best that I have for now. I am updating this post to include more world samples.
"Más vale tarde que nunca"
Thoughts?
How should I deal with 1.14 in the near future? (Introduces bamboo jungles and will mess up this)
Small sample size [as yet?] as indicated, and someone well versed in the world gen code needs to confirm that checking the "biome [that] appears at the exact center of the map" does not introduce a bias, but probably a good first cut at the problem.
(I don't see anything that immediately contradicts the BVI [By Visual Estimation] results from the even smaller sample at which I have looked. )

(I don't see anything that immediately contradicts the BVI [By Visual Estimation] results from the even smaller sample at which I have looked. )
It's impossible for any point in the world to produce a bias, because, unlike the pre-1.7 terrain type, the world is homogeneous. If I sent you a picture of a seed, you won't be able to tell where in the world is more likely for me to have taken that picture. Because this, and because the world generation code allows worlds to generate infinitely, we can say that the exact center of a seed is exactly like travelling really, really far in any other seed. It's the same principle of the 'you can find any posible combination of numbers, infinitely repeated, in the decimals of Pi, because they are infinite'
(sorry for my terrible English, it's not my main language)
Anyone knows how to upload images in posts? (big, not small at the end)
pd: forest is a really ugly biome there's too much of it
For a large image, it would be best to show a 'thumbnail' in the post that links to the full sized image; this makes the thread load faster and allows those readers not interested in the larger view to save bandwidth.
Doing this involves storing the image off-site (generally on an image hosting service). There are many of these; some available for a fee, others free. While 'you get what you pay for' remains true, some of the free hosting services are reliable and quite sufficient for many purposes. [Note that you will generally need to create an account on the hosting site, even the free ones.]
I generally use imgur.com [No affiliation/relationship with the site other than using them as a free image host, YMMV]
The link text you will want will be called something like 'BBCode for forums' and follow this format

How were these values measured? I think it's impossibe for river to be over 4% if beach is less than 3%. Beach is way thicker, and there are lots of islands (with mainly Beach in them) in the ocean as well as small ocean biomes within land near the shore (surrounded with Beach or its variants) that do nothing but increase the %.
For the 0% spawn rate on some of the biomes, does this imply that they are of a very low percentile such as 0.00001% or is this implying that they cannot be found naturally?

See post #10 for a list of those that do not (currently) occur naturally in the overworld, otherwise these are just quite rare.

Maybe you should take samples from each update as they come out to see how rare all the biomes are in the updates, to keep up with the updates (and maybe older updates too?

Shouldn't you remove these since they're not used in overworld generation? It may confuse people.
