The Official Top 40 best-selling songs of 1983

Karma Chameleon,the re-data is wrong, because the single sold 1.35 million on end of 1983 and certificate platinum on October by official Gallup Chart.From 950 thousand to 1.5 million copies the difference does not cover the reason that this particular song was not re-released on massive simple logic..the physical is 150 thousand above to 1.35 million+0.150 thousand=1.5+million copies today..Finally, the charts were calculated using the data of the time. The recalculation does not apply, the same happens with other songs that supposedly sold more.

On Friday on the TV show Janice Long said Karma Chameleon sold nearly a million and a half. This contradicts your figure of 955,000. Who is correct?

Hmm, notwithstanding the comments already made about the Culture Club single, 18 of the top 19 singles listed here were certified Gold by the BPI during 1983 ("Blue Monday" being the exception but I seem to remember Factory weren't interested in certification status at the time).
Back then, Gold status meant 500k records, admittedly based on what was ordered rather than sold over-the-counter, but it's a bit surprising that OCC thinks only the top 3 singles managed to sell that figure.
Either the OCC is under-estimating sales or record shops back in 1983 ordered way too many copies of the biggest-selling records - you'd have thought that they'd have learned their lesson as the year progressed

Why has the list of the biggest selling songs of 1983 been shortened to 40 songs when the previous 80s lists, 1980-1982, had 50???

Temptation by heaven 17 was not number 1
