The Calculated Price Ratios Domain

The Calculated Price Ratios domain provides price ratios calculated from FEWS NET system data.

The Calculated Price Ratios domain is broken into three sections:

1. Search and Filter

You can search by various criteria including:

Data source document: name and organization
Data series: name, description, and metadata

Learn more about search functionality in FDE.

You can filter the available data series using one or more of the following criteria:

Start date and End date: Filters data series by the period dates of all data points within the series. All data series with at least one data point that has a period date inside the date range will be displayed.
Data Series status: Filters data series by active or inactive status. Inactive Data Series have been marked by a data manager as no longer receiving new data. This may be because a change in the way the data is being collected (such as a new source or change in units) warranted starting a new Data Series, or because the data is no longer being collected.
Geographic: Filters by country.

2. Data Selection

Once you have applied your search terms and filters, you will be presented with a list of all available data series that match your criteria. A data series is a collection of related data points from a single data source that are viewable as a single row within a table of data. They represent the change over time of a specific indicator. Data series are presented in table format where each row represents a single data series.

The Calculated Price Ratios domain data selection table includes the following columns:

Name: Name of the data series.
Country: Country for which the price ratio was calculated.
Data source organization: The name of the organization that provided the data source document.
Data source document: The name of the document used as the primary source of information or data.
First: Period date for the first collection/reporting period in the data series.
Last: Period date for the last collection/reporting period in the data series.
Count: The number of data points in the data series.
Info: Hover over the information icon in a row to see more details including the data series ID, data source document, and data usage policy.

To visualize and export data, you will need to select one or more data series by checking the box at the beginning of the row containing that series.

In addition to selecting data series, you can interact with the data selection table in the following ways:

Selected data series can be viewed in the Selected tab.
You can clear your selections using the Clear Selected button.
By default the series are ordered alphabetically by country. You can click on the header of any column to sort by that column instead of by country.

3. Data Visualization and Export

Visualize

The Calculated Price Ratios domain currently includes Chart and Table visualizations.

If you have selected dates in the filter section, these visualizations will only contain data points with an associated period date within the specified date range. Data points within the selected data series with a period date outside of the specified date range will not be displayed.

The Chart tab in the Calculated Price Ratios domain displays a line graph where each data series is represented by a line of a different color. The chart plots the USD per Domestic Currency (y-axis) against time (x-axis).

You can interact with the chart in the following ways:

Hover over a line to see more details including specific values.
Single click on a legend item to exclude it from the graph.
Move the sliders in the bar below the graph to zoom in or out, or use the zoom buttons above the graph to zoom to a specific length of time (e.g., 3 months or 5 years).
When zoomed in, drag the slider bar below the graph to change the time period you are viewing.
Click the download icon in the top right to download the chart or to view it in full screen.

Customize

Customization options within the Calculated Price Ratios domain allows for aggregation or conversion of the data. The available parameters are:

Reporting Schedule: Provides reporting options on a daily, weekly, monthly, quarterly and annual basis. The default reporting schedule is monthly.

Export

The Calculated Price Ratios domain includes the following options:

File format: Choose from one of the available file formats. This will apply to both downloads and refreshable links.
Download: Provides a download of a static dataset. This will export only the data series that you have selected.
Copy link: Copies a refreshable link that connects directly to the FEWS NET Data Warehouse database server, allowing Excel, your browser, or another application to automatically fetch data from the server whenever the link is accessed.
