That did it. Thanks very much.

Thank you for the clarification, however I followed your instructions and the data did not get into Mailchimp. I created the mu-plugins folder and uploaded the s2-hacks.php file which contained the following:

<?php
add_filter('ws_plugin__s2member_mailchimp_merge_array', 'my_filter', 10, 2);
function my_filter($merge, $vars) {
	// $merge: Array of existing MERGE fields that s2Member passes by default.
	// $vars:  Array of defined variables in the scope/context of this Filter.

	$custom_merge = array(
		'ID'   => get_user_field('ID', $vars['user_id']),
		'Role'   => get_user_field('Role', $vars['user_id']),
		'Registration Date'   => get_user_field('Registration Date', $vars['user_id']),
		'Auto-EOT Date'   => get_user_field('Auto-EOT Date', $vars['user_id']),
		'Nick_Name' => get_user_field('Nick_Name', $vars['user_id']),
		'birth_date'   => get_user_field('birth_date', $vars['user_id']),
		'Street_Address' => get_user_field('Street_Address', $vars['user_id']),
		'Address_2nd'   => get_user_field('Address_2nd', $vars['user_id']),
		'City' => get_user_field('City', $vars['user_id']),
		'State'   => get_user_field('State', $vars['user_id']),
		'Zip' => get_user_field('Zip', $vars['user_id']),
		'Home_Phone'   => get_user_field('Home_Phone', $vars['user_id']),
		'Other_Phone' => get_user_field('Other_Phone', $vars['user_id']),
		'Spouse_Name'   => get_user_field('Spouse_Name', $vars['user_id']),
		'spouse_birth' => get_user_field('spouse_birth', $vars['user_id']),
		'Directory'   => get_user_field('Directory', $vars['user_id']),
	);

	return array_merge($merge, $custom_merge);
}

And I received the following email from Mailchimp after their confirmation email.
