Start with the answer

Library Technicians pay in Des Moines-West Des Moines, IA and Seattle-Tacoma-Bellevue, WA

The May 2025 BLS OEWS median for Library Technicians is $46,840 per year in Des Moines-West Des Moines, IA. It is $65,690 per year in Seattle-Tacoma-Bellevue, WA. Des Moines-West Des Moines, IA is 28.7% below Seattle-Tacoma-Bellevue, WA on the published median.

Both rows use SOC 25-4031 and the same annual wage metric. Median means the middle of each area's published wage spread. It is not one worker's pay. The larger median is not proof that one place gives a better job or a better result. It is one wage fact from one source period.

BLS lists 310 wage and salary jobs in Des Moines-West Des Moines, IA and 1,290 in Seattle-Tacoma-Bellevue, WA. Those are survey job counts, not open posts. Read pay, job scale, local share, and price level as separate facts before you make a choice.

Pay range

Compare the full Library Technicians wage ladder

A median can hide a wide range. The 10th, 25th, 50th, 75th, and 90th percentile points show more of each area's spread. A percentile is a rank point. It is not a career stage. The 10th point does not mean new-worker pay. The 90th point does not mean a wage that comes after a set number of years.

The lower half can differ from the upper half. One area can lead at the median and trail at another point. Read each field against the same field in the other area. Do not compare one area's 75th percentile with the other area's median. That would answer a different question.

A posted job range can sit below, across, or above these marks. That does not make the post wrong. A listing can differ by employer, level, hours, field, or work rules. Keep the listing tied to that employer. Keep the BLS range tied to the whole role-place row.

Shape of pay

Mean and median tell two parts of the Library Technicians story

Des Moines-West Des Moines, IA has a mean of $47,450 per year and a median of $46,840. Seattle-Tacoma-Bellevue, WA has a mean of $66,910 per year and a median of $65,690. Mean adds all wage values and splits the total by the number of jobs behind the estimate.

Des Moines-West Des Moines, IA's mean is 1.3% above its median on the same published median. Seattle-Tacoma-Bellevue, WA's mean is 1.9% above its median on the same published median. The gaps show that each wage spread has a shape. They do not explain why the shape differs.

Use median for the middle. Use mean to see how the full set pulls. Use percentiles to see more of the spread. None of the three is a pay promise. A person, team, or listing can sit far from all three for reasons that are outside these BLS rows.

Job scale

How the two Library Technicians job bases differ

Des Moines-West Des Moines, IA has 310 estimated Library Technicians jobs. Seattle-Tacoma-Bellevue, WA has 1,290. The larger count shows a larger covered job base in this source. It does not show more open roles, faster hiring, or a better chance for one applicant.

Des Moines-West Des Moines, IA has 0.77 Library Technicians jobs per 1,000 local jobs. Seattle-Tacoma-Bellevue, WA has 0.62 per 1,000. This rate helps compare places of different size. It is not a job-post rate and does not use the MeritLog catalog.

The employment RSE is 9.1% in Des Moines-West Des Moines, IA and 0.6% in Seattle-Tacoma-Bellevue, WA. RSE means relative standard error. It is a survey precision flag. It is not the chance that the job count or one person's pay is right.

Local share

Where Library Technicians takes a larger share of jobs

The location quotient is 1.74 in Des Moines-West Des Moines, IA and 1.39 in Seattle-Tacoma-Bellevue, WA. A value of 1 means the role has the same share of local jobs as it has across the nation. A value above 1 means the local share is larger. A value below 1 means it is smaller.

Des Moines-West Des Moines, IA's quotient is 25.2% above Seattle-Tacoma-Bellevue, WA's. That gap is about the job mix. It is not a wage gap, a job-count gap, or a growth claim.

Read location quotient with employment. A small place can have a high share and few jobs. A large place can have many jobs and a share near the national mark. Then read pay as its own field. The three measures do not form one score.

BEA price view

How price levels differ between Des Moines-West Des Moines, IA and Seattle-Tacoma-Bellevue, WA

BEA's 2024 all-items price index is 91.7 in Des Moines-West Des Moines, IA and 111.1 in Seattle-Tacoma-Bellevue, WA. The U.S. level is 100. A higher number means the broad local price level is higher than the national mark. It does not say a place is good or bad.

Housing is 84.7 in Des Moines-West Des Moines, IA and 151.3 in Seattle-Tacoma-Bellevue, WA. Goods are 93.7 and 104.0. Utilities are 84.6 and 92.8. Other services are 92.9 and 106.8. The parts can move in different ways.

The wage period is May 2025. The price period is 2024. WageScope keeps those clocks visible. It uses the all-items index for one clear proxy. It does not mix BEA prices into the BLS source row, and it does not claim the two releases describe the exact same month.

Price-level proxy

Compare the medians in national-price dollars

WageScope divides Des Moines-West Des Moines, IA's $46,840 median by 91.7 divided by 100. The result is $51,079 per year. It divides Seattle-Tacoma-Bellevue, WA's $65,690 median by 111.1 divided by 100. That result is $59,109 per year.

Des Moines-West Des Moines, IA's proxy is 13.6% below Seattle-Tacoma-Bellevue, WA's. The nominal gap is 28.7%. The order can stay the same or change after the price-level step. Both results must keep their labels.

The proxy is a narrow math tool. It is not take-home pay. It does not add taxes, benefits, household size, debt, commute, schools, safety, climate, or taste. It does not set a wage target. Use it to see how one broad price index changes the wage view, then check your own costs outside WageScope.

Same-proxy pay

What equal price-level pay would look like in the other place

$46,840 per year in Des Moines-West Des Moines, IA has the same national-price-dollar proxy as $56,766 per year in Seattle-Tacoma-Bellevue, WA. The math keeps Des Moines-West Des Moines, IA's proxy fixed, then applies Seattle-Tacoma-Bellevue, WA's all-items price index.

$65,690 per year in Seattle-Tacoma-Bellevue, WA has the same proxy as $54,204 per year in Des Moines-West Des Moines, IA. This reverse view is useful because the answer depends on which wage you start with. It is not a claim about an offer in either place.

Equivalent nominal pay uses one broad price measure. It does not know what a person buys. It does not know rent, family size, debt, taxes, travel, benefits, or savings. Treat the result as a clean source-backed comparison, not a full move plan or a number an employer must match.

Data care

Check the survey marks before you use the gap

The mean-wage RSE is 2.3% in Des Moines-West Des Moines, IA and 0.3% in Seattle-Tacoma-Bellevue, WA. The employment RSE is 9.1% and 0.6%. RSE is a precision flag for the field it sits beside. It is not a score for the whole page.

BLS does not publish the same RSE field for the median and each percentile. WageScope does not move a mean RSE to the median. It does not use an employment RSE as a wage care mark. Each value stays tied to its source field. Missing or top-coded values also keep their source state.

A later BLS or BEA release can change the result. MeritLog checks the official source clocks before promotion. The page cannot call its data current when a newer complete release is waiting for review. Current job cards have their own seen date and do not make the government data newer.

Use the result

A short check list for Des Moines-West Des Moines, IA and Seattle-Tacoma-Bellevue, WA

Start with the same Library Technicians wage field. Then read the full percentile spread. Check job count, jobs per 1,000, and location quotient. Add the 2024 all-items and housing price levels. Read the national-price-dollar proxy with its limits. Keep the BLS and BEA dates in view.

Next, inspect one current employer-title match in each place when an exact public place match exists. A job post can show work level, hours, location rules, and pay that the BLS row cannot. The post is dated employer evidence. It does not change the survey median or prove a broad trend.

Last, use your own facts. Compare the job needs with work you have done and can support. A wage gap cannot show fit. A price-level gap cannot show fit. A job count cannot show fit. MeritLog's résumé path starts only after you choose a listing and confirm the work facts you want to use.

Limits

What this Library Technicians comparison does not decide

The page does not choose Des Moines-West Des Moines, IA or Seattle-Tacoma-Bellevue, WA for you. It does not say what one worker earns. It does not promise a job, offer, raise, or move result. It does not say why the medians differ. It does not turn the larger wage, job count, quotient, or proxy into a place score.

The comparison leaves out people who work for themselves and other work outside the OEWS scope. It does not add taxes, take-home pay, benefits, stock, bonus pay, hours, travel, remote work, or a household budget. Current listings are separate and can be empty even when the government rows are complete.

Use this page for a bounded choice. Compare the same May 2025 BLS role and metric across two exact areas. Add the separate 2024 BEA price view. Inspect dated employer-title matches. Then build a résumé from facts you have confirmed. Keep each source tied to the question it can answer.
