we saw the simulation what it we just observe
we observed that homophily sort of emerges
please note the chapter the discussion has
been of homophily so do you observe that there
is some sort of a homophily here right there
is a lot of people who sort of get together
and theyah cluster together now do you observe
something in fact it is startling to see thatlocal
behaviour results in a global structure what
do i mean by that a local behaviour such as
one person trying toah decide about his locality
andtrying to shift to a better locality person
who is trying to see if he has a good neighbours
if he doesn't have the required number of
neighbours he shifts to a different locality
he he is just trying to do something locally
but he each and every person doing this it
results in a global phenomena correct
so we observe that there is this emergence
of homophily here but that is this homophily
or segregation inevitable what do i mean by
this probably my next figure that i am going
toshow you we will make it clear is this homophily
inevitable will it always happen not really
and why do i says look at this beautiful examplehere
are a few people right green and red in fact
for t equals three you observe that everybody
is actually happy everybody has three neighbours
who are like them correct so observe it carefully
every green has three green neighbours every
red has three red neighbours you can filled
the entire grid like this this is not a lot
of clustering here all though there is some
kind of clustering there is lot a lot of clustering
here people in fact are living harmoniously
with each other there are both types of people
and there is no high because segregation here
and still they do satisfy this property of
the threshold being three which means they
have the required number of neighbours but
segregation is not happening
now this is a surprising factor that all though
there is a possibility that segregation need
it happen segregation does happen most of
the time it is observed that in on themap
of some countriespeopleah basically aredistributed
evenly rather i mean uniformly at random but
later on this slowly drift and you see this
patterns of segregation emerging all in all
schelling model beautifully captures the this
notion of a people getting segregated and
rises many questions like can we come out
to the nice mathematical model to explain
this which remains to be an open question
till date
