The information requested falls within the responsibility of the UK Statistics Authority. I have asked the authority to reply.Letter from Karen Dunnell, dated July 2009:"As National Statistician, I have been asked to reply to your Parliamentary Question asking how many (a) men and (b) women were in employment in the Hemsworth constituency in (i) May 1997 and (ii) May of each year since 1997. (288662)""The Office for National Statistics (ONS) compiles employment statistics for local areas from the Annual Population Survey and its predecessor the annual Labour Force Survey (LFS) following International Labour Organisation (ILO) definitions. Estimates for local areas are only available on an annual basis.""Table 1, attached, shows the number of people in employment aged 16 and over by gender, resident in the Hemsworth constituency. Estimates are provided for the 12 months ending in February from 1998 to 2004 from the annual LFS, and for the 12 months ending in December from 2004 to 2008, from the APS.""As these estimates are for a subset of the population in small geographical areas, they are based on small sample sizes, and are therefore subject to large margins of uncertainty."<Table width="100%" summary="" cellspacing="3" cellpadding="3" border="0"><thead><tr><th>Table 1: Men and women in employment¹ in Hemsworth parliamentary constituency</th></tr></thead><TR><TD>Thousand</TD></TR><TR><TD>12 months ending</TD><TD>Men</TD><TD>Women</TD></TR><TR><TD>February 1998</TD><TD>18</TD><TD>15</TD></TR><TR><TD>February 1999</TD><TD>20</TD><TD>15</TD></TR><TR><TD>February 2000</TD><TD>18</TD><TD>15</TD></TR><TR><TD>February 2001</TD><TD>20</TD><TD>18</TD></TR><TR><TD>February 2002</TD><TD>21</TD><TD>16</TD></TR><TR><TD>February 2003</TD><TD>26</TD><TD>16</TD></TR><TR><TD>February 2004</TD><TD>25</TD><TD>18</TD></TR><TR><TD>December 2004</TD><TD>22</TD><TD>18</TD></TR><TR><TD>December 2005</TD><TD>20</TD><TD>18</TD></TR><TR><TD>December 2006</TD><TD>25</TD><TD>20</TD></TR><TR><TD>December 2007</TD><TD>22</TD><TD>20</TD></TR><TR><TD>December 2008²</TD><TD>***22</TD><TD>***17</TD></TR><tfoot><TR><td>¹ Levels of employment are provided for persons aged 16 and over.</td></TR><TR><td>² Coefficients of Variation have been calculated for the latest period as an indication of the quality of the estimates.
