Social maps that reveal a city's intersections — and separations
-
0:01 - 0:02When we think about mapping cities,
-
0:02 - 0:05we tend to think about roads
and streets and buildings, -
0:05 - 0:08and the settlement narrative
that led to their creation, -
0:08 - 0:11or you might think about
the bold vision of an urban designer, -
0:11 - 0:13but there's other ways
to think about mapping cities -
0:13 - 0:16and how they got to be made.
-
0:16 - 0:18Today, I want to show you
a new kind of map. -
0:18 - 0:19This is not a geographic map.
-
0:19 - 0:22This is a map of the relationships
between people in my hometown -
0:22 - 0:24of Baltimore, Maryland,
-
0:24 - 0:28and what you can see here is that
each dot represents a person, -
0:28 - 0:31each line represents a relationship
between those people, -
0:31 - 0:35and each color represents a community
within the network. -
0:35 - 0:40Now, I'm here on the green side,
down on the far right where the geeks are, -
0:40 - 0:44and TEDx also is down
on the far right. (Laughter) -
0:44 - 0:46Now, on the other side of the network,
-
0:46 - 0:49you tend to have primarily
African-American and Latino folks -
0:49 - 0:53who are really concerned about somewhat
different things than the geeks are, -
0:53 - 0:54but just to give some sense,
-
0:54 - 0:57the green part of the network
we call Smalltimore, -
0:57 - 0:58for those of us that inhabit it,
-
0:58 - 1:01because it seems as though
we're living in a very small town. -
1:01 - 1:03We see the same people
over and over again, -
1:03 - 1:05but that's because
we're not really exploring -
1:05 - 1:08the full depth and breadth of the city.
-
1:08 - 1:10On the other end of the network,
-
1:10 - 1:13you have folks who are interested
in things like hip-hop music -
1:13 - 1:17and they even identify with living
in the DC/Maryland/Virginia area -
1:17 - 1:21over, say, the Baltimore city
designation proper. -
1:21 - 1:23But in the middle, you see that there's
-
1:23 - 1:26something that connects
the two communities together, -
1:26 - 1:26and that's sports.
-
1:26 - 1:30We have the Baltimore Orioles,
the Baltimore Ravens football team, -
1:30 - 1:31Michael Phelps, the Olympian.
-
1:31 - 1:34Under Armour, you may have heard of,
is a Baltimore company, -
1:34 - 1:36and that community of sports
acts as the only bridge -
1:36 - 1:39between these two ends of the network.
-
1:39 - 1:40Let's take a look at San Francisco.
-
1:40 - 1:44You see something a little bit
different happening in San Francisco. -
1:44 - 1:48On the one hand, you do have
the media, politics and news lobe -
1:48 - 1:51that tends to exist
in Baltimore and other cities, -
1:51 - 1:53but you also have this
very predominant group -
1:53 - 1:57of geeks and techies that are sort of
taking over the top half of the network, -
1:57 - 2:00and there's even a group
that's so distinct and clear -
2:00 - 2:02that we can identify it
as Twitter employees, -
2:02 - 2:06next to the geeks, in between
the gamers and the geeks, -
2:06 - 2:08at the opposite end
of the hip-hop spectrum. -
2:08 - 2:10So you can see, though,
-
2:10 - 2:13that the tensions that we've
heard about in San Francisco -
2:13 - 2:16in terms of people being
concerned about gentrification -
2:16 - 2:19and all the new tech companies
that are bringing new wealth -
2:19 - 2:21and settlement into the city are real,
-
2:21 - 2:23and you can actually see
that documented here. -
2:23 - 2:25You can see the LGBT community
-
2:25 - 2:28is not really getting along
with the geek community that well, -
2:28 - 2:30the arts community, the music community.
-
2:30 - 2:32And so it leads to things like this.
-
2:32 - 2:33["Evict Twitter"]
-
2:33 - 2:35Somebody sent me this photo
a few weeks ago, -
2:35 - 2:38and it shows what is happening
on the ground in San Francisco, -
2:38 - 2:40and I think you can
actually try to understand that -
2:40 - 2:42through looking at a map like this.
-
2:42 - 2:44Let's take a look at Rio de Janeiro.
-
2:44 - 2:46I spent the last few weeks
gathering data about Rio, -
2:46 - 2:49and one of the things
that stood out to me about this city -
2:49 - 2:51is that everything's
really kind of mixed up. -
2:51 - 2:55It's a very heterogenous city in a way
that Baltimore or San Francisco is not. -
2:55 - 2:58You still have the lobe of people involved
-
2:58 - 3:00with government, newspapers,
politics, columnists. -
3:00 - 3:03TEDxRio is down in the lower right,
right next to bloggers and writers. -
3:03 - 3:06But then you also have this
tremendous diversity of people -
3:06 - 3:08that are interested
in different kinds of music. -
3:08 - 3:11Even Justin Bieber fans
are represented here. -
3:11 - 3:13Other boy bands, country singers,
-
3:13 - 3:16gospel music, funk and rap
and stand-up comedy, -
3:16 - 3:19and there's even a whole section
around drugs and jokes. -
3:19 - 3:21How cool is that?
-
3:21 - 3:24And then the Flamengo football team
is also represented here. -
3:24 - 3:26So you have that same kind of spread
-
3:26 - 3:29of sports and civics
and the arts and music, -
3:29 - 3:31but it's represented
in a very different way, -
3:31 - 3:34and I think that maybe fits
with our understanding of Rio -
3:34 - 3:38as being a very multicultural,
musically diverse city. -
3:38 - 3:42So we have all this data.
-
3:42 - 3:45It's an incredibly rich set of data
that we have about cities now, -
3:45 - 3:48maybe even richer than any data set
that we've ever had before. -
3:48 - 3:50So what can we do with it?
-
3:50 - 3:53Well, I think the first thing
that we can try to understand -
3:53 - 3:55is that segregation is a social construct.
-
3:55 - 3:59It's something that we choose to do,
and we could choose not to do it, -
3:59 - 4:01and if you kind of think about it,
-
4:01 - 4:04what we're doing with this data
is aiming a space telescope at a city -
4:04 - 4:07and looking at it as if was
a giant high school cafeteria, -
4:07 - 4:11and seeing how everybody arranged
themselves in a seating chart. -
4:11 - 4:14Well maybe it's time to shake up
the seating chart a little bit. -
4:14 - 4:17The other thing that we start to realize
-
4:17 - 4:19is that race is a really
poor proxy for diversity. -
4:19 - 4:22We've got people represented
from all different types of races -
4:22 - 4:25across the entire map here --
-
4:25 - 4:27only looking at race
-
4:27 - 4:30doesn't really contribute to
our development of diversity. -
4:30 - 4:32So if we're trying to use diversity
-
4:32 - 4:35as a way to tackle some of our
more intractable problems, -
4:35 - 4:38we need to start to think
about diversity in a new way. -
4:38 - 4:41And lastly, we have the ability to create
-
4:41 - 4:45interventions to start to reshape
our cities in a new way, -
4:45 - 4:47and I believe that if
we have that capability, -
4:47 - 4:50we may even bear some
responsibility to do so. -
4:50 - 4:52So what is a city?
-
4:52 - 4:54I think some might say that it is
-
4:54 - 4:57a geographical area or a collection
of streets and buildings, -
4:57 - 5:00but I believe that a city
is the sum of the relationships -
5:00 - 5:02of the people that live there,
-
5:02 - 5:08and I believe that if we can start to
document those relationships in a real way -
5:08 - 5:09then maybe we have a real shot
-
5:09 - 5:12at creating those kinds of cities
that we'd like to have. -
5:12 - 5:13Thank you.

- Title:
- Social maps that reveal a city's intersections — and separations
- Speaker:
- Dave Troy
- Description:
-
Every city has its neighborhoods, cliques and clubs, the hidden lines that join and divide people in the same town. What can we learn about cities by looking at what people share online? Starting with his own home town of Baltimore, Dave Troy has been visualizing what the tweets of city dwellers reveal about who lives there, who they talk to — and who they don’t.
