The world is a pretty crowded place and if you haven't worked that out by now, then you should probably give it a second thought. While there may be places like Russia that are the complete opposite of the locations we're about to list, for the most part, overpopulation is a very real issue that can create an abundance of issues for people on a day to day basis.
From major cities to inner suburbs and remote islands, there are some major problems that have been created by overpopulation and it's something that needs to be reviewed by leaders around the world. As you'll see throughout this list there are some cities that will be separate to their own suburbs which will feature, due to the figures involved which make for a 'bigger picture'.
The numbers have all been calculated on a people per mile squared spectrum, although the populations obviously vary. You see, that's one of the biggest mistakes that people tend to make when it comes to somewhere being 'densely' populated - it really doesn't matter how big or small the destination is, because it can serve as a massive hassle all the same.
Most of you reading this will likely be lucky enough to live somewhere that doesn't feel all too claustrophobic, but even if you do, maybe that's something you enjoy. It's not everyone's cup of tea, but surrounding yourself with large volumes of people can sometimes be comforting.
Either way, we are hoping that this list really gets you thinking.
20 Dhaka, Bangladesh - 121,700 people per sq. mile
Dhaka is one of those cities that has beauty hidden deep within it, but that also suffers from a string of different problems. There are nice areas dotted around the city but for the most part, it's completely overrun in terms of the population and that shows no signs of slowing down.
From an economic standpoint, it's no secret that Bangladesh isn't a particularly wealthy country for the most part, either, and while they may not suffer quite as much as some of their neighbouring countries, it's still something that needs to be recognised as we continue on through the list.
19 Manila, Philippines - 107,561 people per sq. mile
The Philippines is a nation that's going to feature quite heavily in this and any other list of this nature, and in short, it's a country that seems to try and fit too many clowns in the car - and we don't mean that in a disrespectful manner, it's just the first analogy that popped into our head.
The capital, Manila, is quite modernised and really embraces the Spanish culture, even more so than other cities around the nation. However, if you look a little closer, you'll see an overwhelming amount of individuals living in homes that just aren't worthy of housing even one person let alone a family.
18 Ebeye, Marshall Islands - 107,143 people per sq. mile
When over half of your population is under the age of 18, you know there's something a little unusual going on.
Ebeye is a well-populated island in the Marshall Islands with more than 15,000 residents, but given how astronomically small the area is for that amount of people, you can imagine how crowded it gets. It's probably much more fun than some of the alternatives we've listed given the youth movement as well as the scenery, but if you're a local, it must get pretty annoying sometimes.
After all, 80 acres of land is hardly going to keep you going forever.
17 Mumbai, India - 73,837 people per sq. mile
Mumbai is undoubtedly one of the hot spots for those who are trying to live a life of luxury in India, which continues to be one of the fastest growing countries in the world (and, unsurprisingly, will, therefore, feature quite a lot).
From being the heart of the Bollywood boom to having several great architectural gems, it's no wonder that millions flock to the city every year. Alas, the initial plan probably didn't involve so many people actually staying there after their visit, as their 18 million strong population keeps getting bigger and bigger.
One thing is for sure, we don't want to experience their traffic.
16 Bnei Brak, Israel - 73,159 people per sq. mile
While Israel as a nation is gradually becoming more and more modern with each and every passing day (see the fact that they're hosting Eurovision next year as a perfect example of that), there are still areas where they fully embrace their Jewish heritage to the maximum.
Bnei Brak is one such example, with the ultra-Orthodox taking up residence here in the last few hundred years. Given its small size, though, they weren't really prepared for the vast quantities of people that decided to set up shop within their borders, which has caused quite a few issues in the interim.
15 Caloocan, Philippines - 72,302 people per sq. mile
We head back over to the Philippines for their fourth most populated city, which should tell you all that you need to know given the land mass is around 5,333.40 hectares. In many ways, this serves as the equivalent of having a whole city living in one building, and while it isn't literally that dramatic, we aren't far off with our estimation.
Caloocan leaves us to wonder just how just enjoyment you can get from living in a place like this. Sure, you can still have an okay quality of life and there are some great places to go and visit, but feeling that 'closed in' isn't something that many people will consider to be ideal in the slightest.
14 Levallois-Perret, France - 68,458 people per sq. mile
We head to our first suburb of the great city of Paris, and as we noted in the introduction, the city itself will feature later on - and we can explain why. While every city has suburbs, there are very few that have specified areas as populated as Paris, which is why we've felt the need to highlight the figures involved.
In Levallois-Perret you can go and check out the Arc de Triomphe and Place Charles de Gaulle, but when you do, remember that the number of tourists you're seeing pales in comparison to how many people actually live there. It really is staggering, and yet, nobody seems to bat an eye when it's brought up.
13 Le Pré-Saint-Gervais, France - 67,047 people per sq. mile
We have to travel around three or four miles outside of the city centre in order to arrive at our next Paris-based destination, but it's equally as baffling given that the area really isn't that small. It seems as if people think that living slightly outside of the city will give them some kind of 'advantage' in terms of the traffic and housing situation, but they'd be oh so wrong.
It should come as no surprise that there are 10 major schools littered throughout Le Pré-Saint-Gervais, which is just utterly bizarre given that only 17,000 people or so live here. Just take a second to imagine how difficult it would be to stand out in some of these schools. Madness.
12 Chennai, India - 66,961 people per sq. mile
From the outside looking in Chennai certainly seems to provide locals with a more glamorous way of life than most Indians are used to, but of course, that's not something that really holds up once you delve a little further into the story.
There's a substantial pollution issue there which is hardly going to be a surprise, although it is considered to be the health capital of the country which ensures that the locals remain in relatively good shape - if they're able to get to the local doctors or hospital, that is.
It's definitely appealing as a travel destination, but make sure you do some research before heading here.
11 Vincennes, France - 66,371 people per sq. mile
We're heading back over to France now, and more specifically, you guessed it, Paris. Vincennes is slightly further out than any of the other communities we've already mentioned, and while you'd think that would ensure it isn't visited nearly as frequently, you'd be sadly mistaken.
It's a beautiful area and you won't find many who will dispute that, but what good is it if you can't sit back and enjoy it as it's intended? We aren't going to pretend like you can't still have a good time here but it just isn't a place that was ever designed to house so many civilians.
10 Kolkata, India - 62,813 people per sq. mile
You're definitely going to have noticed a theme by this point as we switch back and forth between India and Paris, but that's because the issue is so much more prevalent there (unless you don't consider it an issue, in which case, we'd strongly advise you to Google the effects of overpopulation).
From the colonial architecture to the many great festivals there's a lot to love about Kolkata, and the density isn't quite as bad as some of the others we've listed - meaning that we'd certainly suggest you should come and check it out if you're on a tour of the country.
9 Saint-Josse-ten-Noode, Belgium - 62,404 people per sq. mile
For some reason it feels like the Belgians are skating by on Brussels having a really great reputation as a top European city. We've never been able to understand that and while we've often thrown the 'chocolate and politics' stereotype out there, a much wider issue is certainly in play.
As you can see by the housing situation above there are way, way too many people living in Saint-Josse-ten-Noode, and it's a perfect example of how neglectful a big city can be towards some of their local residents. Perhaps they themselves wouldn't consider the problem to be that bad, but it certainly feels like something that needs to be looked at.
8 Kathmandu, Nepal - 61,972 people per sq. mile
Nepal is a remarkable country in more ways than one, and it allows you to experience a completely different culture to the one that you're probably used to. In this image alone you can see what it's like to be enveloped by the oncoming mountaintops, which is something Nepal is renowned for.
The situation isn't necessarily as extreme as the alternatives in Kathmandu, but the earthquake back in 2015 definitely set them back a few years. They've been rebuilding and reconstructing some of their more historical locations, and hopefully, they'll be back on their feet as a city before too long.
7 Neapoli, Greece - 60,186 people per sq. mile
No, this isn't a misspelling for Napoli - this is Neapoli, located in Greece. When looking out onto the sea it gives off the impression of being nothing more than a traditional seaside destination amongst the many Greek islands, but as you turn to land, the situation becomes that much more puzzling.
The community seems to be slowly growing, perhaps because so many people view it as somewhere that's nice to settle down. In reality, though, they end up with a 'this town isn't big enough for the both of us' kind of scenario. Or, you know, a less immature comparison.
6 Montrouge, France - 59,705 people per sq. mile
Montrouge is one of those interesting sections of Paris that has endured the 'major decline, major rise' effect that the city seems to have been through in the last few decades. It wasn't really considered to be a noteworthy commune for quite some time, but its natural beauty and historical significance has allowed it to become much more prominent.
Whether it be due to the prices there or just because it's near the centre, more and more people have decided to move their lives to good old Montrouge.
Who knows, maybe in the next five years it'll go in the opposite direction, but that seems unlikely at this stage.
5 Malé, Maldives - 59,559 people per sq. mile
If you're going to complain about living somewhere like Malé, even with the slight overpopulation issue, then we've got some destinations that we'd like to inform you of.
The Maldives is home to the rich and the famous throughout the summer months and beyond, but on top of that, Malé is an island that appears to be tucked away as if it's been created on Sim City. From the popular fishing market to the mosques and colourful buildings, it's hard not to look at this place and think of it as somewhere that's completely isolated from the rest of the planet.
4 Malabon, Philippines - 58,607 people per sq. mile
You know that things are getting out of control when you've got a city within another city. That's the situation that we find ourselves in with Malabon, which is situated just north of Manila - to the point where it's still considered to be a part of the capital.
It's officially a part of the Metro Manila area, which was actually created to try and deal with the growing population issue. Given the direction that the world is going in it doesn't seem as if it's going to have made too much of a difference, but as long as we're doing everything we can to cut out any poverty, that's all that matters.
3 Guttenberg, United States - 58,577 people per sq. mile
Guttenberg is the sole representative for the United States of America and it's not exactly hard to see why, based on that image alone. At only four blocks wide Guttenberg is astonishingly small, although the fact that it's just a stone's throw away from The Big Apple should explain its popularity.
We never quite know how to feel or act towards cities or towns like this, because while they are getting the opportunity to live right next to arguably the greatest city in the world, you have to question what they need to sacrifice just to be able to afford living here.
2 Paris, France - 55,673 people per sq. mile
We've come to the granddaddy of them all after looking through some of the more specific suburbs - Paris. The city of romance has many different faces, and locals will tell you that one of those 'overriding' faces is the worst case of overpopulation in Europe.
It's not as if it's the smallest city in the world, either, it's just that so many people both from abroad and around France are deciding to build a life for themselves there. It's never going to be something that we pay too much attention to from the outside looking in, but once you're there, it's hard to ignore.
1 Macau, China - 54,790 people per sq. mile
Macau just about qualifies as a city that 'gets away with it' in terms of the population density, although it's something that the local government should be keeping an eye on. The uniqueness of this destination, given that it qualifies itself as a 'Chinese special administrative region', is probably what intrigues us the most about it.
There's so much mystery around the city and yet, more and more locals are popping up with each and every passing year. They like to march to the beat of their own drum, and bizarrely enough, that's something that we can respect and admire.
