meaning of make-up

[Learning_English]

They argue that the membership of the Council does not reflect the racial make-up of the city.
Organizational ability is not one of the most obvious parts of his make-up.

I can't quite understand the meaning of "make-up" in these contexts. Could you explain it to me?

Hi,

'Racial make up' refers to the composition of the different races within the city - the percentages of each one.

'parts of his make up' refers to the different aspects of his personality and character.

Thank you friends.
So I understand the above two sentences as :
(1) They argue that the membership of the Council does not include the composition of different races of the people.
(2) Organization ability is a different one that can learn only by experience; so it is not one of the most obvious parts of the different aspects of his personality.
Please help me. I am awaiting your reply.

1-- ...does not accurately include the same proportions of the races
2-- The original says nothing about learning from experience, it only says that the man is not very good at organizing.
