It is possible to stablish links between formal and informal economies and the flow of money between sectors.

Data
The data presented was collected by observational and direct surveys (face-to-face) to street vendors in Cali, Colombia in two street vending sites. First study was conducted during December 2014 in the city downtown. Second study was conducted in 2016 in Santa Helena Market. In both studies street vendors answered questions concerning socioeconomic status, family composition, income (including sales and profits), education, life satisfaction, and access to government welfare. The survey was randomly collected, anonymous, and voluntary.

Experimental design, materials and methods
According to the local government, there are nine sites in the city where street vendors conduct their economic activity (see Fig. 1marked in red). The study took place in two sites: Centro and Santa Helena, the most populated areas in the city in terms of street vendors and formal commerce. Street vending in downtown (centro) covers an important array of cheap merchandise from footwear to cell phone accessories. Santa Helena is a food market.
Two types of data were collected: observational and survey data (Figs 2 and 3 present the details). The former was collected using a standardized observational format which collected information on: types of stalls (fixed or mobile), type of products offered, number of people working at a stall, and an indicator of the physical condition of the stall (physical condition was defined as good, fair and poor and its classification was based on the condition of each stall as perceived by the observer). This information allowed to count total number of street vendors and proxy to the occupation in public space. Second type of data was survey information. Respondents answered questions concerning socioeconomic status, family composition, income (including sales and profits), education, life satisfaction and access to government welfare. This information is used to construct variables about business operation and profitability and socioeconomic conditions of street vendors Analysis using this information has been published (Martinez et al., 2017).
