I tweeted this out last night while watching old reruns of Anthony Bourdain's Parts Unknown series. This was a great show. If I were to give everything up and become a YouTuber, this is the kind of travel and food channel I would want to make, except that I would naturally have to add in some equal parts around architecture, planning, and real estate.

The responses to my tweet were of course mixed. Some people agreed and some people didn't. And a few people provided examples of great cities that aren't particularly known for their openness to new entrants -- places like Tokyo. This kind of response is not at all surprising given how divisive this topic has always been throughout history.

But here's what I was thinking:

1/ There are some obvious current case studies. Consider places like Toronto and Miami, where foreign born residents now make up the majority of the population. These are two fast growing and dynamic cities that wouldn't be anywhere near as interesting without their immigrant populations. Certainly the food wouldn't be as good.

2/ Many of the most beautiful cultures in the world are the result of different cultures coming together. Brazil is one example that comes to mind. Throughout history they have been one of the largest recipients of immigrants in the western hemisphere. Sadly, Brazil was also the last country in the western world to abolish slavery.

3/ Rome and Tokyo were cited (in the comments) as two great cities that frankly aren't all that diverse. According to Wikipedia, less than 10% of Rome's population is non-Italian. But Rome, while nice, is provincial these days. And Tokyo, while awesome, has a bit of a demographic problem.

4/ Even if you think a place doesn't have a lot of immigrants and maybe isn't all that diverse, it is still probably the result of diverse cultures coming together at multiple points throughout history. Maybe because of immigration. Or maybe because of something bad like war. Think of the Moors from northern Africa who crossed the Strait of Gibraltar and conquered the Iberian Peninsula.

5/ An openness to new people could signal and probably does signal an openness to other things. And since we are living in a world that thrives on innovation and new ideas, being open strikes me as being a fairly good and useful characteristic to have.

6/ Lastly, I come from a family of immigrants. I self-identify as being entirely Canadian. But I had to come from somewhere (multiple places, in fact). And so it strikes me as being odd and entirely selfish to want to block the flow of people now that I'm here and established.

What are your thoughts?

I just discovered this set of maps (via Brian Potter) looking at the largest cities in the world from 100 CE all the way through to today (well 2015 CE). Here are what the two bookends of this map series look like:

It is an interesting reminder of just how centralized the world was around the Mediterranean and parts of Asia, and also how nothing is guaranteed. As recent as 1900, cities like Manchester and Philadelphia were among the top 10 largest cities. Today they aren't even close.

UPDATE: The data behind these maps has been called into question. Look out for a follow-up post.

“The city has to be for everybody, not just for the very few.” -Paulo Mendes da Rocha

Brazilian architect, Paulo Mendes da Rocha, died this past weekend. He was 92. Though he hadn't really completed many buildings outside of his home country, his work and his contributions to São Paulo are widely celebrated. Some of his accolades include the Mies van der Rohe Prize for Latin American Architecture (2000), the Pritzker Prize (2006), the Venice Biennale Golden Lion for Lifetime Achievement (2016), and the Royal Institute of British Architect's Royal Gold Medal for Architecture (2017). I've always had a soft spot for Brazilian modernism. They were early adopters of European modernism and ultimately made it their own. I don't think Mendes da Rocha would necessarily appreciate this classification, but as I've mentioned here before, modernism, and more particularly brutalism, took on very different qualities in Latin America. Exposed concrete just seems to hit differently in a tropical setting. Here and here are some examples of his more famous projects.
