The Secondary Price Index (SPI) domain provides…..The SPI Indexes domain provides consumer price indices and other price indices not calculated by FEWS NET.
The Secondary Price Indexes 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
...
Start date: Returns all data series starting on or before this date.
...
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.
Searching and/or applying filters creates a savable dataset. For more information on creating and saving datasets, see Create and Save Datasets.
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
