Sql join, count references including zeros

I made a simple database containing two tables, ‘country’ and ‘human’:

+------+---------+
| id   | name    |
+------+---------+
|    1 | Finland |
|    2 | Sweden  |
|    3 | Norway  |
|    4 | Denmark |
+------+---------+

+--------+----------+
| name   | homeland |
+--------+----------+
| Liisa  |        1 |
| Matti  |        1 |
| Holger |        2 |
+--------+----------+

This query shows that nobody lives in Norway, but why it says nothing about Denmark?

select country.name, count(human.name)
from human
    right join country on human.homeland = country.id
group by homeland;

+---------+-------------------+
| name    | count(human.name) |
+---------+-------------------+
| Norway  |                 0 |
| Finland |                 2 |
| Sweden  |                 1 |
+---------+-------------------+

I am using MariaDB, but prefer solutions that works on other DBs too.

Answer

You typically GROUP BY the same columns as you SELECT, except those who are arguments to set functions:

select country.name, count(human.name)
from country 
    left join human on human.homeland = country.id
group by country.name;
