How do I combine COUNTIF with OR

Question

In Google Spreadsheets, I need to use the COUNTIF function on a range with multiple criteria. So in the table below, I would need to have something like =COU

Answer 1

you can use regex like this:

=ARRAYFORMULA(SUM(N(REGEXMATCH(B:B, "Mammal|Bird"))))

Answer 2

You can also use ArrayFormula around a SUM(COUNTIFS()) construct:

=ArrayFormula(SUM(COUNTIF(B:B,{"Mammal", "Bird"}))

Answer 3

One option:

=COUNTIF(B:B; "Mammal") + COUNTIF(B:B; "Bird")

According to the documentation:

Notes

COUNTIF can only perform conditional counts with a single criterion. To use multiple criteria, use COUNTIFS or the database functions DCOUNT or DCOUNTA.

COUNTIFS: This function is only available in the new Google Sheets.

Example:

=DCOUNTA(B:B; 2; {"Type"; "Mammal"; "Bird"})
