A dotted value moved sharply against the previous observed value in its series, which is the usual signature of a series break or a source revision; it is a prompt to check, not a judgement. The last row, On the profile, is the figure the country profile shows today, set under its series so the two can be checked against each other. ≠ marks a difference of more than 2%: none on this page.
