This is corroborated by the fact that LDCs account for 15 per cent of global migrant stock but their share in global remittances was only 5.7 per cent. An International Organization for Migration (IOM) survey (IOM 2010) found that annual remittance per migrant worker was only USD 1,672 for Bangladesh whilst the figures for India, China and Philippines were USD 4,843, USD 6,112 and USD 4,982 respectively. The 2010 IOM survey found high correlation between education level and remittances sent by Bangladeshi migrant workers.
