Rosa lives in the Patio Bonito settlement on the southwestern periphery of Bogota. Each day she travels over an hour each way to reach her workplace in a well-off family’s home near the Central Business District. There are reasons to stay in the neighborhood, however. One of the main among many: she rarely feels like she is on her own here in this community of neighbors and extended family with whom she moved here many years ago when Patio Bonito was just beginning to form.

For households with low or unreliable incomes, informal networks of social relationships can help increase day-to-day wellbeing and make it easier to cope with crises. Partly for this reason, networks have been found to influence the decisions of households to migrate from rural areas to cities and to continue to drive their subsequent intra-urban mobility.
Taking
into account the roles and the spatial distribution of relational networks can
improve our understanding of housing consumption decisions and inform urban policies.
As I found out through early interviews with Bogota’s public officials in
charge of housing policies, the importance of personal support networks for the
quality of life of low-income households is a major influence and constraint on
their willingness to relocate and can therefore also affect the rate of uptake
and long-term economic sustainability of public housing projects.
To understand what are the
trade-offs that low-income households in Bogota are willing to make between
living near their extended family networks and improving their residential
environment along other dimensions, I implemented an original choice experiment
and a survey in two of Bogota’s low-to-medium income localities, Bosa and
Kennedy, an area where the majority of residents rely on informal or unstable
incomes and where dense informal residential settlements surround one of the
first formally planned affordable housing communities.
The choice experiment
showed that the surveyed individuals prioritize proximity to their extended
family more than accessibility to the Central Business District. As might be
expected, those who have relied on help from extended family members in a
personal or economic crisis situation have a stronger preference for living
near extended family compared to those who have not, as do those who are able
to rely on extended family ties for various resources.
New
urban realities, such as the urbanization of poverty
in developing countries, call for residential location choice explanations that
are not restricted to physical housing quality and transport costs to the
workplace but also take into account factors related to the decision-makers’
social preferences and dependencies. By combining quantitative location choice
modeling and social network analysis, my research places an important economic decision
– that of housing consumption – in a social context and expands the notion of
‘economic rationality’ by more thoroughly characterizing the livelihood
strategies of the poor.
The
empirical evidence on the high value placed on proximity to family networks can
help inform a number of urban policy decisions, for example, the choice between
in-situ slum upgrading and large-scale population resettlement and the design
and spatial location of formal affordable housing to ensure that they are able
to accommodate ‘extended households’ or at least provide good connectivity to
those parts of town where most of their new residents are likely to relocate
from.
