Completed - 1889 US immigration - what do these numbers mean ?

[SiGr]

Hi, Does anybody have any idea what the arrowed numbers mean on this US immigration passenger manifest from 1889 ? If I go by the arrowed column heading, it should be, "Date and cause of death". But the "36  18" makes no sense - unless there were 36+ causes of death, which might be the simple answer.  But this particular sailing was also not at sea on the 18th - so that discounts the 18 being a date. And what would the '0' mean for either option ? Also confusing, I know at least one person with numbers in this column did not die on the voyage. NB variants of these 'double figures' appear on about 10% of the passengers. As always, all suggestions/ideas welcome. Thank you.

Hi,
Sorry, but not a clue!

It represents the numbers of males and females of a particular nationality on the page. There is one male from the USA and no females ( 1 - 0 ) and 36 males from Sweden and 18 females. ( 36 - 18 ).
The numbers are totalled at the bottom left of the page - 37  males of all nationalities  , 18 females and 55 all together.

Hi, Christine53, A big thank you for that. I have had a look on other pages and it all 'adds up'. I would never have worked it out. The 'date and cause of death' column had me thinking that it was 'Midsomer Murders at Sea' given the huge number who seemingly died en route. Now it all makes sense. Thank you !
