OPFs vs National Averages
At risk of poverty
In 2018, the at risk of poverty rate was for general population was 14%, a reduction of 1.7% on 2017 figures.

EU Survey on Income and Living Conditions (SILC) data 2013
Published February 2013, 2011 and 2010 Revised Results
The Survey on Income and Living Conditions (SILC) in Ireland is a household survey covering a broad range of issues in relation to income and living conditions. It is the official source of data on household and individual income and also provides a number of key national poverty indicators such as the at risk of poverty rate and the consistent poverty rate.
The EU-SILC figures for 2013 show that one parent families continue to experience a disproportionate level of poverty. It is important to note that one parent families in the context of the EU-SILC data refers to parents who are divorced separated, widowed and parents who have never been married.

- Lone parent households continue to be at a high risk of poverty with a rate of 28.4% being recorded for individuals in these households. This is compared to a 16% at risk of poverty rate in the general population.
- Lone parents represent 7.3% of the population.
- 18.8% of children are at risk of poverty; they experience the highest rate of consistent poverty compared to other population groups (those over 65 years and the 18-64 age cohort).

Growing Up in Ireland Survey 2013
The Growing Up in Ireland survey, initiated by Treoir, is an on-going national longitudinal study of children in Ireland. Data has been collected on a large cohort of infants (11,134), who were nine months old when the data was collected in 2008/9, and their parents. Treoir commissioned an analysis of the data relating to unmarried parents. Data was collected on lone unmarried parents and unmarried cohabitant parents. Outcomes for these groups were compared to those for married families who were the ‘reference category’ in the study. Data on crisis pregnancy was also analysed. The full report is available on www.treoir.ie/policy
Crisis Pregnancy
- 16.4% of women experienced an ‘unintended pregnancy’, while just under 16% of women experienced a ‘stressful’ pregnancy, where this stress was solely due to the pregnancy itself.
- Women whose pregnancies were both unintended and stressful at the same time are labeled as experiencing a ‘Pregnancy Crisis’. This group comprised 3.4% of women in the sample.
- Marital status is significantly associated with crisis pregnancy, with unmarried-cohabitant parents 3 times more likely than married parents to experience crisis pregnancy and solo parents 4-5 times more likely.
Solo Parents
- Solo Parents are two and a half times more likely than married parents to live in a household where anyone was receiving some form of social welfare payment.
- Three out of every ten Solo parents (27.7%) were claiming One-parent family payment.
- Solo parents are 10 times more likely to be welfare dependent, 9 times more likely to be on Rent Supplement and half as likely to as married parents to have been on Jobseeker’s Benefit.
- Fared worse on every measure of deprivation
Father’s Involvement
- Fathers in unmarried-cohabiting families were significantly more likely to share parenting duties than were married fathers
- Among solo parents, one quarter had no contact whatsoever with the father of their child.
- Among solo parents, 50% of fathers made no financial contribution to the maintenance of their child.
