In other words. there is very little difference between the bills. so far as the total number of persons is concerned. Under the House bill there are what are known as IRO displaced persons. those who are under the IRO. IRO simply means International Refugee Organization. which is an organization under the United Nations. Under the House bill there are 297.000 persons in the IRO category. under the Kilgore bill 295.000 persons. Under the McCarran bill a change in the definition of a displaced person is employed to include IRO displaced persons. plus about 8.000.000 expellees of German ethnic origin.
