I ran a glm looking at population changes over years, and am unsure which results I need to include for a poster presentation. I understand the p value is important for significance but other than that what numbers are necessary and how would I report them?

I do not completely understand what each of the values mean. I am trying to show how populations have changed over the years. I am trying to say something in a university poster along the lines of "I found there to be an overall increase in the population from 2015-2021 (p=0.00155)" but I'm unsure what else would go in the brackets.
