                  Abstract
                  Child  labour  practices  is  considered  as  one  of  the  problems  pertaining  to
                  children in many countries in the world and Ghana is no exception. To combat
                  the situation, many research studies have been undertaken using different
                  modelling techniques with the framework of generalized linear model (GLM).
                  However, the GLM approach fails to capture the spatial heterogeneity that
                  exists  in  the  relationship  between  the  child  labour  practices  and  related
                  factors. The study addresses this gap by exploring the spatial heterogeneity in
                  child  labour  practices  and  its  determinant  in  Ghana  using  geographically
                  weighted linear model (GWLM). This study used Ghana Living Standard Survey
                  Round  6  (GLSS6)  data  collected  in  2012  by  Ghana  Statistical  Services.  The
                  target population was children aged 5‒17 years. GLM was used as a starting
                  point for selecting the appropriate predictors. Moran’s I statistics was tested
                  to ensure the presence of the spatial autocorrelation in the dataset under the
                  null hypothesis of spatial auto correlation. Several factors including proportion
                  of  children  in  school,  proportion  of  aged  household  head,  number  of
                  household head in construction sector and proportion of household head in
                  agricultural  sector  were  considered  in  the  models.  It  was  showed  that  the
                  GWLM  was  useful  and  established  that  there  is  a  spatially  non-stationary
                  relationships between the proportion of child labour and the covariate at the
                  district  level.  The  findings  highlight  the  importance  of  taken  the  spatial
                  heterogeneity into consideration.

                  1.  Introduction
                      Child labour is a phenomenon that exists in the world (ILO-IPEC & Diallo,
                  2013; International Labour Organization, 2013).
                      Thus, the estimates of such conventional models may be bias and could
                  lead to misleading conclusion that may not be beneficial when addressing
                  policy  issues  that  have  a  wider  impact  (Li,  Wang,  Loiu,  Bigham,  &  Raglad,
                  2013).  It  is  important  to  consider  spatial  variations  in  the  analysis  of  child
                  labour practices and its determinants in a wider study area. Such analysis will
