This paper empirically examines the applicability of the planetary urbanization concept to understand the complexities associated with the rural-to-urban transformation process unfolding in India. It contributes to the rural-urban debate by investigating the role of non-urban spaces – here census towns – in accelerating India's process of urbanization. The Capital Region of India is taken as a study area and a mixed methods approach is used to establish concentrated and extended urbanization as interlinked processes in relation to the growth of census towns. The applied mixed methods approach helps to overcome the critiques of deploying Global North theories, here planetary urbanization, on the Global South context by not only establishing a general pattern and dynamics of growth but also by contextualizing the local characteristics of rural to urban transformation as census towns. The analysis established a dense network of transport and a high level of commuting for work between statutory towns and census towns in the urban periphery and hinterland overcoming the traditional urban and rural divide. This paper makes a methodological and analytical contribution to the concept of planetary urbanization, whereby growth of census towns can be explained as an interlinked process of concentrated, extended and differential urbanization. The political economy analyses established that the differences between statutory and census towns can be traced back to state rescaling and investment policies. In this process, rural areas are rapidly acquiring urban characteristics as census towns and to some extent perform better on socioeconomic and infrastructural aspects compared to statutory towns (official urban areas).
