At the same time, in countries where 10-20% of pre-school age children were excluded (Denmark, Hungary, Italy, Latvia, Malta, and Slovakia), there were no significant differences by income. However, missing values for Austria and Bulgaria are relatively low (7 per cent), while data for Sweden (35 per cent) need to be interpreted with extreme caution. There are no significant differences by income for the oldest age group, except in Slovakia, where poor children were more likely to be excluded. This helps construct the profiles of multiply deprived and/or poor children, identifying the most vulnerable sub-groups.
