Statistical Terms Glossary

A price index defined as the weighted arithmetic average of the current to previous period price relatives using the values of the base period as weights. The price reference-period is the previous period (that is the period immediately before the current period) and the weight reference-period is some other fixed period prior to the previous period. A time-series index is derived by chaining which, because the weight reference-period remains fixed, can result in a serious upward drift in the index when price changes are large and erratic.

“Save and grow” promotes a productive agriculture that conserves and enhances natural resources. It uses an ecosystem approach that draws on nature’s contribution to crop growth – soil organic matter, water flow regulation, pollination and natural predation of pests – and applies appropriate external inputs at the right time and in the right amount to improved crop varieties that are resilient to climate change and use nutrients, water and external inputs more efficiently. Increasing resource use efficiency, cutting the use of fossil fuels and reducing direct environmental degradation are key components of the approach, saving money for farmers and preventing the negative effects of overusing particular inputs.

Saving represents that part of disposable income (adjusted for the change in pension entitlements) that is not spent on final consumption goods and services. It may be positive or negative depending on whether disposable income exceeds final consumption expenditure, or vice versa.

Detailed data on sales of consumer goods obtained by ‘scanning’ the bar codes for individual products at electronic points of sale in retail outlets. The data can provide detailed information about quantities, characteristics and values of goods sold as well as their prices.
