Begin by introducing the variables you wish to discuss. Offer a brief definition of each (i.e., what is meant by ethnicity as opposed to race).
Then, describe how these variables have structured your experiences, your outlook, your relationships with others, and – possibly your life outcomes. Has your income (or the income level of your parents, for example) had any effect on your opportunities? On your friendships?
On your health? On the likelihood of relocating at some point?
How has your religious background structured your relationships?
Has your race or ethnicity affected your opportunities?
Your interactions with other people?
Does your marital (or parental) status shape your experiences, your relationships, your opportunities? If so, how?
There are many, many angles to take here.
