The digital economy is transforming how data is collected, processed and used for 
evidence-based decisions to monitor and achieve the Sustainable Development Goals. Promising new methods that combine traditional household survey data with non-traditional data sources (such as mobile phone data, satellite data and text data) are creating opportunities to map poverty at a higher resolution and scale. Nonetheless, significant technical, practical and ethical challenges still hamper the operationalization of these methods.
“The careful combination of ground truth surveys with an abundance of big data increases—not decreases—the value of surveys.”
that the rural population in LAC is decreasing in relative terms. In 2001, official figures indicated that 125 million people in LAC resided in rural areas representing 24% of the total LAC population. In 2013, this value decreased to 21% (130 million out of a total population of 609 million inhabitants), and it is estimated that by 2030, the rural population will decrease to represent 16.5% of the total (CEPAL, 2014).

Goals (SDGs). It helps us to focus policies and make better decisions. It is needed to set targets, measure progress towards those targets and to hold governments accountable to their commitments under the SDGs.
leaders and laggards. Through institutional reform that leverages the advantages of digitalization, the Mashreq can become a vital hub in international data networks. Furthermore, digital transformation can assuage pressing challenges. It can deliver higher transparency, accelerate lackluster productivity and increase economic opportunities for all, especially the youth of this region. A new report,

Where fishing communities once thrived, all that remains is a scarred, desert landscape. Rusted ships are perched precariously on piles of sand and salt, along with a potent, unhealthy mix of toxic pollutants from industrial agriculture.
Sustainable Development Goals. To design and optimize projects for poverty reduction, we need to measure their impact on poverty. This is quite difficult because changes in the poverty rate might take some time, and it is usually hard to attribute the impact to a particular project, especially without conducting a randomized controlled trial (RCT). But even if we manage to overcome these challenges, we need to measure poverty before the start of the project – as a baseline and to understand whether the project adequately targets the poor – and at the end of the project to assess its impact. And that is also not easy.
