        abstract = {Cities in Africa have been described as drivers of economic development but also as disconnected and sprawling, thus constraining their potential to reap agglomeration benefits. One of the urban expansion phenomena associated with shortcomings of urban form is informal urban growth. To find empirical evidence for the question, whether unplanned areas contribute more to sprawl than planned areas in growing African cities, this study will focus on the street accessibility dimension of sprawl. Connectivity metrics of urban locations will be used to compare unplanned and planned areas in Tanzanian secondary cities. A linear regression model with spatially clustered standard errors is used to trace the isolated effect of planning type on compactness. Results suggest that this effect is not homogenous across cities. Two types of cities are identified, where for one the effect of planning type is found to be significant. Further research on informal urban expansion in developing countries might be encouraged to take the methodology and results at hand into account when addressing the perceived shortcomings of informal urban morphologies.}
