group. Four additional quarterly follow-up surveys followed in May 2009, August 2009, November 2009, and February 2010. In March 2012 a final, longer-term follow-up survey was conducted. We include the 397 baseline control group enterprises in our sample and use data from all six survey waves.

Using information from round to round, we coded _survival_ in each round to one if:

- the owner said that he or she was still owning and operating a business, and the line of the business had not changed; or

- the line of the business had changed, but when asked what happened to the business previously ran, the owner said that he or she was either operating the same business, or that the business was now being run by another family member; or

- the owner or a person knowledgeable of the matter told the enumerator that the owner was still operating the business, if the respondent refused to participate in the survey or could not be located; or

- the owner or a person knowledgeable of the matter told the enumerator that he owner was not operating the business anymore but that someone else was operating it, if the respondent refused to participate in the survey or could not be located.

We coded _survival_ to zero if:

- the line of the business had changed, and when asked what happened to the business previously run, the owner said that the business had closed down, had been modified to become the current business, or gave any other answer that implied the closure of the original business; or

- the owner or a person knowledgeable of the matter told the enumerator that the business had closed down, if the respondent refused to participate in the survey or could not be located.

We coded _newfirmstart_ to one, if the line of the business had changed from one round to another and the respondent said that his or her main activity was then operating a different business. Otherwise, we coded _newfirmstart_ to zero.

To be able to assess survival of firms operating at baseline, we recoded _survival_ in a final step, by recoding it to zero for all subsequent rounds, if it had been coded as zero in a given round and a new firm start had been coded in the same round or later.

_Kenya GET Ahead Business Training Program Impact Evaluation Survey (KEGETAHEAD)_ The survey was part of an evaluation of a business training program for women in four counties of Kenya: Kakamega and Kisii in the Western region, and Embu and Kitui in the Eastern region. In each county a census was taken of all female-owned businesses in market centers deemed as medium-sized or large, and then a screening was done to select a sample in which the business did not have more than 3 employees; the business had profits in the past week between 0 and 4000 Kenyan Shillings (KSH) (1 US Dollar averaged approximately 85 KSH over the survey period); sales in the past week less than or equal to 50,000 KSH; and the individual had at least one year of schooling. The survey is therefore representative of microenterprises of this size run by women in these four counties.

The baseline survey took place between June and November 2013, and included 3,537 individuals. These individuals were then assigned to treatment and control for the business training intervention in a two-stage process, with markets being assigned to treatment or control in the first stage, and then, within markets that had been assigned to treatment, individuals being assigned to treatment or control. We include all control group observations, i.e. individuals in 48
