Here is the Wiki description. They have a black Friday.
“Capital punishment is legal in Singapore. The city-state had the second highest per-capita execution rate in the world between 1994 and 1999, estimated by the United Nations to be 13.83 executions annually per hundred thousand of population during that period. The highest was Turkmenistan (now an abolitionist country) with 14.92. Each execution in Singapore is carried out by hanging in Changi Prison at dawn on Friday.”
I linked to the citation.
The number should be 14 per 1,000,000, not 14 per 100,000.
So, the actual rate is 70 per year, not 700.
Plus, they have a footnote at the link.
They estimated Singapore's population at 3.5 million.
In fact, the population in the late 1990’s was about 5 million, so that brings the number of executions down even more.
Just bad luck on your link.
I find Wiki to be exceptionally reliable on published data, almost 100% of the time.
