Demographic transitions

Today in class, we talked more about demographic transitions which is a model that describes population change over time. we watched two videos and we learned about the five stages of the models and what each means. countries used to be at a stage one model and now most are at a stage 3 or 4 model which means that our population is almost at a constant rate of change. We read over the paper from yesterday and read through each stage of the demographic transitions. Then, when we watched the videos, we paused every so ofter to talk about the use off the sentence that was being told and we learned about the different categories each stage has.
