Calculation of the required points corresponding to the AWU percentage bands

The AWU percentage bands are:

WH_MAN_AWU_PC1T24_POINT     WH_MAN_AWU_PC25T49_POINT     WH_MAN_AWU_PC50T74_POINT     WH_MAN_AWU_PC75T99_POINT

WH_HLD_AWU_PC1T24_POINT     WH_HLD_AWU_PC25T49_POINT     WH_HLD_AWU_PC50T74_POINT     WH_HLD_AWU_PC75T99_POINT     

FLF_D_RFAM_M_PC1T24_POINT     FLF_D_RFAM_M_PC25T49_POINT     FLF_D_RFAM_M_PC50T74_POINT     FLF_D_RFAM_M_PC75T99_POINT     

FLF_D_RFAM_F_PC1T24_POINT     FLF_D_RFAM_F_PC25T49_POINT     FLF_D_RFAM_F_PC50T74_POINT     FLF_D_RFAM_F_PC75T99_POINT     

FLF_D_RNFAM_M_PC1T24_POINT     FLF_D_RNFAM_M_PC25T49_POINT     FLF_D_RNFAM_M_PC50T74_POINT     FLF_D_RNFAM_M_PC75T99_POINT     

FLF_D_RNFAM_F_PC1T24_POINT     FLF_D_RNFAM_F_PC25T49_POINT     FLF_D_RNFAM_F_PC50T74_POINT     FLF_D_RNFAM_F_PC75T99_POINT

If you do not know the AWU for each person:   you can use the simplest approach to report the centers of the intervals i.e. 0.125, 0.375, 0.625, 0.875. 

If you know the AWU for each person:  please use the following approach:

• For each percentage bands separately, sum up the AWUs of all persons classified in that percentage band.
• For each percentage bands separately, divide the sum of AWUs to the number of persons classified in that percentage band.  
  The result is the required point of the AWU percentage band. 

If we know these points at Eurostat, we can use them to calculate the correct total AWU of the persons (by percentage band or overall).

At Eurostat, we know the number of persons falling in each AWU percentage band. If we multiply this number of persons by your calculated point, we obtain the correct total AWU of the persons. Instead, if we multiply this number of persons by the centers of the intervals i.e., 0.125, 0.375, 0.625, 0.875, then our calculated total AWU will differ from your calculated total AWU.  Therefore, this serves to reduce the discrepancies of data on labour force published at national and EU level.
