Human variation means you can be a male with a natural “male” wide pelvic bone. When determining the sex of human skeletons, they use a whole array of measurements besides just the width of the pelvis and still get it wrong sometimes. Unless you have other indications or feel you might be a different gender than you present as, you have nothing to worry about.
What subject do you want to create a bibliography for?
Sidewalks where I live are bumpy, interrupted by trees, signposts and trash bins and occupied by pedestrians. Much better (and ultimately safer) is to cycle in the middle of the lane to force cars to give you space. You are also more visible that way to cars from sidelanes.
Unoccupied land is otherwise called “nature” and is quite useful for a lot of things.
