In 1974, the National Accounts Staff of the National Economic and Development Authority initiated the Regional Income Accounts Project for the purpose of presenting the regional disaggregation of the nation's domestic products. The dearth of statistics at the regional level, however, prevented the project from presenting the inflow and outflow of goods for the various regions. In 1976, an Inter Agency Committee on Transportation and Communication Statistics (IACTCS) was created to develop a rational and integrated statistical system for the combined sector. The Committee was chaired by NEDA with National Statistics Office (formerly National Census and Statistics Office), Bureau of Customs (BC), Philippine Ports Authority (PPA), Maritime Industry Authority (MARINA), Ministry of Public Works, Transportation and Communication (MPWTC), Philippine Airlines (PAL), and Philippine National Railways (PNR) as members.
