Economy

1.     Average Household Debt

2.     Modified Gross National Income at current market prices per capita (GNI*)

Source: National Income and Expenditure

In July 2016, the Central Statistics Office released the National Income and Expenditure accounts for 2015. These figures showed that the economy grew by 26.3% in 2015. The reporting of GDP is a requirement under EU law and must be compiled strictly in accordance with international rules. The figures published were based on hard data and attributable to the globalisation activities of a very small number of companies.

The core issue relates to the insights on our changing domestic economy that can be gained from the key economic indicators of GDP and GNP in a small, open and highly globalised economy – perhaps the most globalised in the world. Moreover, GDP and GNP, although required internationally, no longer provide a sufficient understanding of the domestic economy of Ireland and need to be supplemented with a broader suite of indicators that can provide the necessary insights.

A group of experts was being convened to undertake this work, and developed Modified GNI (or GNI*). GNI* is defined as GNI less the effects of the profits of re-domiciled companies and the depreciation of intellectual property products and aircraft leasing companies. This new indicator of the level of the Irish economy is a useful additional input to debt ratio analysis.

Despite this work, GNI* is a modified national economic indicator, and is not intended to be used as a sole measure of societal well-being.

8.     Percentage working longer than 48 hours per week on average

21.  Equality of income distribution

Source: Survey of Living Conditions

Gini coefficient

This is the relationship between cumulative shares of the population (ranked according to the level of income from lowest to highest) and the cumulative share of total income received by them, i.e. the Lorenz Curve.  If there was perfect equality (i.e. each person receives the same income) the Gini coefficient would be 0%.  A Gini coefficient of 100% would indicate there was total inequality and the entire national income was in the hands of one person.

25.  Prevalence of Overweight/Obesity

Source: Healthy Ireland

As an important determinant of health, data on weight and height were gathered in the Irish Health Survey, from which the Body Mass Index was then calculated. Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight and obesity in adults. It is defined as the weight in kilograms divided by the square of the height in metres.

To be classified as overweight, a respondent’s BMI would need to be greater or equal to equal 25 and less than 30. A BMI of 30 or more is classified as obese.

Full details of these data can be found here.

26.  Prevalence of binge drinking
