The Indigenous Peoples (IP) Data and Development Program is a CIPO initiative that aims to produce comprehensive demographic data for IP living in Cambodia. At present government data relating to IPs in Cambodia is inconsistent and flawed. In 2009 the Statistics of National Policy of Indigenous People placed the number of indigenous people at 179,000, 1.34% of the population, whilst in 2013 the Inter-Censal Population Survey stated that 2.3% of total population were Indigenous based upon the number of households that speak their mother tongue. Both figures are in contrast to the United Nations Population Fund (UNFPA) survey of 2008 that stated 383,273 IPs were living in Cambodia, or the Commune Data Base statistic of 2015 that counted 276,878 IPs. Such inconsistencies continue between different governmental departments: in 2013 the National Institute of Statistics (NIS-MOP) released figures that stated 10 provinces had 16 indigenous groups whilst in 2015 the Ministry of Rural Development (MRD) stated that there were 24 Indigenous groups in 15 provinces. CIPO believes that confusion in the concept of and categorization of ‘Indigenous People’ has created misleading official statistics that understates IPs numbers and creates a bias against IP development projects. From 2016-2017 CIPO, processed and consolidated existing IP data through discussion with relevant stakeholders and members of Cambodia Indigenous Peoples Alliance (CIPA). This concurred with a meeting held in January 2017 between officials from 16 ministries and IPs to reflect upon the Implementation of the National Policy on Indigenous peoples development of 2009, and a working group was established to implement the policy: key strategic actions were identified and the terms of reference developed. In March 2017 CIPO presented their findings to the MoP who agreed to generate, analyze and produce further official statistics on the demographic and Socio-economic status of IPs in Cambodia with an agreed publication date of March 2018.
