Each square represents
a language or language
group, in this case
English. The top square
is the most integrated.
EMBARK | DATA SHEET
Groups were identified
by the languages used
in tweets; Twitter users’
neighborhoods were
identified based on
where they most
often stay overnight
(8 p.m. to 8 a.m.).
Highly integrated Moderately integrated
How integration
is measured
London, for
example...
About one-third of the analyzed cities are
linguistically diverse and have relatively
high rates of integration.
London and a handful of global cities have
linguistically diverse populations and few
self-segregated ethnic neighborhoods.
(*) FRENCH SPEAKERS IN MONTRÉAL
ALSO SPEAK ENGLISH.
CITIES WITH RESIDENTS TWEETING
IN FEWER THAN THREE LANGUAGES
ARE NOT SHOWN.
London is marked by high
integration among the
largest range of languages
identified on Twitter (24).
Nagoya, Japan, has
10 non-native language
groups; members of five
of them are well integrated
across the city.
Berlin—among the world’s
more integrated cities—
has the fewest foreign
language groups tracked
in the study.
TWEETS OF MANY TONGUES
BY MONICA SERRANO
has 20 highly integrated
languages or language
groups ( ), meaning
they’re as spread out as
London’s English speakers
are. Three communities
are moderately integrated
( ), while none are
moderately segregated
( ). The city does have
one language group—here,
they’re Arabic speakers—
who tend to live in specific,
distinct neighborhoods
and are thus considered
highly segregated
( ).
