Following is a response from DHS Research & Data Analysis Director, Tom Pullum:

For a trend analysis, I recommend staying with the original weights and NOT doing that equalization step.

Sometimes, for a relatively rare event, users will pool surveys to get more statistical power. (This has to be done with caution, because the pooled population is not usually well defined.) That's a situation in which you might want to give each survey equal weight or change the weights to take account of population size. But when studying trends, I don't think the results would be affected by such changes to the weights, so there's no reason to make those changes.
