Data Analysis
The Data analysis module provides advanced access to all the data that has been published to the FEWS NET Data Warehouse, in addition to data consolidation tools. Its purpose is to allow for detailed inspection of the data for drawing informed conclusions, and to support decision-making.
Module details and operations
The following options are available for the Data analysis module and can be accessed via the Warehouse system menu dropdown:
Single data series: List of all Single data series within the system, regardless of domain category. Selecting a data series within this module will open the selected series within the Data series management module for additional analysis or editing.
Population estimate for shapefiles: A tool to determine the population within a shapefile. To upload and return the population statistics for a shapefile, follow the steps below:
Click Choose File to select a zipped shapefile that meets Esri or .shp standards. Upload the file.
Select the year by which the population will be calculated. For example, to determine the population within the uploaded shapefile in 2001, select 2001 from the dropdown menu.
Indicate whether the output should include a full demographic breakdown. If this box is unchecked, the system will only return the population statistics.
Define whether the output should be calculated using a calibration factor from a user specified data source document.
Click Submit
Data sets: Functions like the Single data series tool above, but instead categorizes the single data series by domain categories. Selecting a data series within this module will open the selected series within the Data series management module for additional analysis or editing.
Calculated data series: List all calculated data series such as relative prices and price indices. There are two types of calculated data series within the FEWS NET Data Warehouse:
Weighted: This calculated data series gives weight to each Data series within the index.
Unweighted: A simple average of the index.
Dashboards: Provides a variety of data visualization dashboards which are outlined below:
Conflict Maps: Visualizes conflict and migration flow data, as well as FIC near term projected outcomes, population data, and trade flow data. Learn more about the Sudan multilayer map.
