		<h1>Global Gender Gap</h1>
		<p> Index values from the World Economic Forum's 2014 Global Gender Gap Report. Countries included in this chart have <a href="https://reports.weforum.org/global-gender-gap-report-2014/part-1/appendix-b-tracking-the-gender-gap-over-time/"/> continuous index vales</a> from 2000-2014. For <em>all</em> 142 countries with 2014 index values, see the WEF's <a href="https://reports.weforum.org/global-gender-gap-report-2014/part-1/the-global-gender-gap-index-results-in-2014"/>full report</a>.</p>
