Major discrepancy in Immigration numbers

Only after I've made the blog posting here, and subsequently read the World Bank's Brain Drain report, I discovered a mistake had been made in my blog. I should have reviewed the World Bank report first instead of just relying on figures from Jabatan Imigresen. That is because there is a huge discrepancy between the Imigresen and the World Bank migration number.

Below are excerpts from both World Bank and Jabatan Imigresen.

Above: Slide presentation from Jabatan Imigresen. The figure of 1.8 million inbound migration is reasonably supported by detailed breakdown of nationality but the outbound migration figure (785,000) is vague and nowhere near World Bank figures.

Above: From the fourteenth and one-hundred-thirty-sixth pages of the World Bank Brain Drain Report- big gap betweenthe two reports.

There is obviously a big difference between 785,000 (Jabatan Imigresen figure) and the 1 million plus (lowest World Bank estimation of outbound migrants). I doubt I have the power to summon the World Bank for detailed workings of their figures but as a rakyat I need to question Jabatan Imigresen and Department of Statistics on the quality of their public presentations.

Look at the quality of 'statistics' published at the Imigresen website here:

It is also obvious that either the quality of employee skills in Jabatan Imigresen and Jabatan Statistik is so bad; or there is a deliberate act to release false data deemed as sensitive to the public. Maybe the Jabatan Imigresen figure of 785,000 is just an 'anggaran' but it's an anggaran so inaccurate that it cannot fit into my regression line*.
