2.8 Undocumented persons who do not fit any of the previous categories 2.8.1 Causation of statelessness Undocumented persons who come from extreme poverty do not have the awareness to register for birth certificates and obtain formal documentation. This is exacerbated by a lack of knowledge on the importance of registering children, which creates challenges in the process of obtaining citizenship. This is evident in the case of Malaysian citizens Nagalingam Ramasamy, 56, and Chellamma Papaiya, 56, whose five children were not able to obtain Malaysian citizenship (Malaysia Nanban, 2017, June 29). In the case of Thenmozhi Ramakrishnan, she did not register the birth certificates of her two children within the stipulated time period set by JPN, and thus rendered them stateless (Malaysia Nanban, 2017, April 27). 2.8.2 Scale of issue The scale of the issue from this category is unknown because the Malaysian government does not collect disaggregated data on noncitizens. They maintain the binary of citizen and non-citizen as a citizenship status so have no breakdown on the number of refugees, migrants, stateless persons or undocumented persons (Parlimen Malaysia, 2019b). 41
