Parity progression ratio and Tempo adjusted Total Fertility Rate

[Tesfay Birhane]

Dear experts, I am Tesfay, conducting research on "Fertility transition in Ethiopia" using the Ethiopian Demographic and Health Survey. I do have two questions:
1. Could someone help me estimate the parity progression ratio from DHS data and what are the steps and commands in Stata?
2. How can I estimate tempo-adjusted total fertility rate TFR adjusted for the changes in the mean age of childbearing between surveys?
Kindly, I appreciate your support in advance.

Dear Stata experts, peace and health to you.
I want to estimate the parity progression ratio using the pooled data of the Ethiopian demographic and health survey (EDHS-2000, 2005, 2011, 2016 & minDHS2019). I am using Stata version 14
I am kindly asking you to share with me a Stata command or syntax for estimating the PPR or show me the steps to do so.
