The supplemental .zip archive for this publication contains the following files. Stata files were created using Version 13 and may not be compatible with earlier versions.
Four country sub-folders:
1. Ethiopia (ET)
2. Kenya (KE)
3. Tanzania (TZ)
4. Zimbabwe (ZW)

Each country files contains the following:
a. Master Stata do-file for birth interval analysis, for example: 
    		Ethiopia_master.do
	And the subset of do-files:
		ET_create_Birthrecode2000
		ET_create_Birthrecode2005
		ET_create_Birthrecode2011
		ET_create_Birthrecode2016
	Which requires the following DHS birth recode data files to be downloaded:
		ETBR41DT
		ETBR51dt
		ETBR61DT
		ETBR70DT

	In addition, you will need to download the individual recode data files and 		extract 	the 'ever use of contraception variable' (v302) and the women's ID 		variable (caseid) and save this data in the following format ET_v302_			20xx.dta
	ETIR41DT
	ETIR51dt
	ETIR61DT
	ETIR70DT

b. A spreadsheet that calculates the fitted estimates for the hazard rates and the median birth interval calculations from the regression models run from the Master do-file. 
				Ethiopia_Fitted_Values.xlsx
In order to replicate the results of our analysis, the coefficients from the stata output for each model need to be pasted into the corresponding cells in revelant excel sheet. The destination cells have been highlighted in colour in the sheet.
