In this webinar in partnership with WorldPop, you learn about how high-resolution data on human population distribution & characteristics are becoming more & more important. You can watch the recorded webinar at: https://go.carto.com/webinars/worldpop-global-demographic-insights

Why High-Resolution Spatial Data on Population Matters

  1. 1. Why High-Resolution Spatial Data on Population Matters Follow @CARTO on Twitter
  2. 2. CARTO — Unlock the power of spatial analysis Introductions Giulia Carella Data Scientist at CARTO Andrew Tatem Director of WorldPop
  3. 3. CARTO — Unlock the power of spatial analysis CARTO is the platform to build powerful Location Intelligence apps with the best data streams available.
  4. 4. CARTO Customers Pioneers in Location Intelligence 1,200 End-users 300K Team members 100+
  5. 5. CARTO — Unlock the power of spatial analysis Agenda ● WorldPop: Mapping population distributions, demographics and dynamics ● WorldPop in CARTO: how do I access the data? ● Why high-resolution population data matters for location intelligence, a tale of two cases ○ Site Planning ○ Supply Chain Management

  13. 13. CARTO — Unlock the power of spatial analysis WorldPop Population Counts ● Global 2000 - 2020 at 1 km resolution ● Global 2000 - 2020 at 100 m resolution
  14. 14. CARTO — Unlock the power of spatial analysis It’s time for a practical session on how to access WorldPop data in CARTO! https://colab.research.google.com/drive/1YW8olUi4Mw5Md71YfofY 6z5zWy2wR37O#scrollTo=ugYv0YOQ3NZ3
  15. 15. CARTO — Unlock the power of spatial analysis Boosting Location Intelligence with WorldPop data Site Planning Site planning is the process of using data to identify locations for opening, closing, relocating or repurposing sites - whether it be stores, branches, ATMs, distribution centres, hospitals or airports. ● Data come in different geographical supports, how can they be combined? ● Location Planning Analysts need data at high-granularity, e.g. demographic, human mobility, and socioeconomic data
  16. 16. CARTO — Unlock the power of spatial analysis Generate high-resolution socioeconomic data Carella et al., accepted to KDD Humanitarian Mapping Workshop https://arxiv.org/abs/2006.13152 ● Human mobility data are available at high resolution. ● Census data are typically not available at scales finer than Census units. ● Downscale key socioeconomic Census variables using WorldPop population counts and geographical data as drivers.
  17. 17. CARTO — Unlock the power of spatial analysis PPC A High-resolution data (150 m x 150 m) Low-resolution data (Census block groups) ● Select a origin location ● Find all the most locations according to a set of variables and a scoring rule Finding similarities
  18. 18. CARTO — Unlock the power of spatial analysis Boosting Location Intelligence with WorldPop data Location Intelligence plays a critical role in Supply Chain Management (SCM) as many of its processes have a very strong spatial component. Some examples of supply chain planning processes with a spatial component are: ● Strategic planning: Facility location, transportation and distribution network design ● Tactical planning: Demand forecasting, last mile distribution areas design ● Operational planning: Routing Supply Chain Management
  19. 19. CARTO — Unlock the power of spatial analysis Calculating Optimal Delivery Areas Based on Distance, Population Counts and DC Utilization
  20. 20. CARTO — Unlock the power of spatial analysis Calculating Optimal Delivery Areas Based on Distance, Population Counts and DC Utilization ● Identify where there is more demand. ● Use a linear optimization model setting the following costs in the objective function: ○ Average distance traveled ○ Deviation from a perfect balance of workload in the DCs during the peak season ○ Deviation from a perfect balance of population covered by DC capacity
