Bloomberg has removed the January (and some of the February) data since June 2013. The removal of the data has been confirmed by the official source, China National Bureau of Statistics (NBS). According to NBS, January data was never available as the reporting of January data is exempted officially. Moreover, official February non-cumulative data for 2012 and 2013 are not released because NBS had internal changes on its statistical reporting system. The January (and some February data) Bloomberg carried prior to June 2013 were provided by a third party distributor authorized by NBS, but NBS has recently confirmed that those numbers are unofficial. This ticker is non-cumulative. As January figures are incorporated into the February values, the non-cumulative figures for January and February figures are not available.
